General

Catch Can Kits

  • My vehicle has an auxiliary fuel filter, will there be room for a Catch Can too?

    That depends on the vehicle. In some cases the two units are installed in completely different locations, in others a dual bracket capable of mounting both units is available. Call us on 1800 880 150 and we can advise you.

  • Can I install the unit myself?

    Yes, all you need is some mechanical aptitude, basic hand tools, and common sense. Our kits come with step-by-step instructions to keep you on track.

  • If this deposit build-up is such a common problem why don’t manufacturers fit a mist separator in production?

    Good question. The answer is a few do..…. but not many. Most manufacturers seem more focused on meeting emission requirements when the vehicle leaves the showroom than they are about the harmful side-effects of the methods used to meet those requirements.

    It may be that, generally speaking, vehicles are built to a price point so things are left off the list.

  • My vehicle is still under warranty, is this effected?

    Aftermarket products can sometimes tempt vehicle manufacturers to look for loop-holes. It’s most unlikely any manufacturer would view a Mist Separator in a negative way, after all, it prevents a known problem.

    If you are in doubt you should discuss the installation and any warranty ramifications with your service advisor.

  • Does a Catch Can have any effect on the roadworthiness of my vehicle?

    No, fitting a Catch Can is completely legal.

  • I’ve seen other brands of separators, why do you use Provent?

    We believe the Provent range of separators are the most efficient design available for mist separation. All air passing through the separator has to pass through a cellulose membrane, effectively filtering out the oil & water vapour.

    The design also has safety features that protect against crankcase over-pressurisation. In short; they are high quality and work well.

  • Catch Cans weren’t needed on older engines, so why are they needed now?

    Diesel engines before around 2002 did not have Exhaust Gas Recirculation (EGR). Before EGR a little oil mist in the intake system presented no real problem. It’s only when EGR was introduced that the problem of carbon deposits raised it’s ugly head.

    Since it’s illegal to disable EGR, the best way to deal with the problem is to remove oil from the recipe.

  • Why do I need an Oil Mist Separator (Catch Can)?

    Essentially; it’s to prevent or reduce carbon deposit accumulation in the intake manifold of engines. This requires some explanation: Modern diesel engines suffer from a condition brought about by an emission control process called Exhaust Gas Recirculation (EGR).

    In the EGR process some exhaust gases are piped to the air intake system, this modifies the combustion process thereby lowering Nitrous Oxide emissions produced. The hot exhaust gas contains carbon (soot) and other by-products of combustion that would not normally attach to the intake manifold if not for another emission control process called Closed Crankcase Ventilation (CCV).

    Crankcase ventilation gases are also piped to the air intake system, this gas contains oil mist and water in the form of condensation. When the crankcase gases from CCV combine with the exhaust gases from EGR, the oil mist mixes with the soot particles to produce a mixture that attaches to the walls of the intake manifold. It’s the combination of the oil with soot that creates the problem.

    These deposits build up over time to a point where they severely restrict the flow of air, causing reduced performance and fuel efficiency. Removing the deposits involves disassembly of the intake system from the engine, both time consuming and expensive.

    By installing an Oil Mist Separator, often called a Catch Can, the oil mist and water vapour are substantially removed from the combination thereby taking away the ingredient that allows the soot to stick. The result is that the build-up of deposits is GREATLY reduced.

  • What is an Oil Mist Separator (Catch Can)?

    An Oil Mist Separator is a device that separates microscopic oil and water particles from air when the air stream is passed through it.

    They are commonly used on internal combustion engines to prevent oil mist, from fumes vented from the engine crankcase, from entering the air induction system. The oil is caught in a vessel, this is where the slang term Catch Can comes from.

Filtration Systems

  • I’ve heard lots of horror stories about dirty fuel. I have also read stories online by “experts” that a secondary fuel filter system could actually create more problems than what they fix, such as not providing enough fuel flow. Comments?

    We have seen some claims by one or two forum experts, one even suggesting the high pressure Common Rail Pump could run dry. This is complete nonsense. In some instances I agree that an inadequate supply causes problems, e.g. some rotary fuel pumps are very sensitive to restriction (Bosch VP44, Denso ECD-3 & ECD-V4).

    But in most systems around today, including Common Rail, secondary (final filtration at 2 to 5 micron) is the best thing you could do to increase the life of your fuel system & safeguard against expensive repairs due to fuel contamination.

    Some modern vehicles e.g. Toyota, have a restriction indicator to alert the driver if there is a restriction by illuminating a warning light on the dash. A restriction sensor mounted on the factory filter senses any restriction upstream from that point back to the tank, but not a restriction downstream of the sensor, i.e. between the factory filter & the high pressure pump.

    In the extremely unlikely case of a secondary filter becoming blocked, the restriction sensor would not detect this, however, the worst thing that could happen by having a reduced fuel flow or restricted supply to the high pressure pump is a loss of engine power, or perhaps a surge.

    These two symptoms are common when a filter becomes blocked, or possibly if a tank puck-up or tank vent is clogged.

    We have never seen a fuel restriction lead to the failure of a Common Rail pump. The evidence that a Secondary Filter will not “create more problems than they fix” is with the tens of thousands of Secondary filters currently fitted to vehicles all over Australia.

    There have been no pump failures, system damage, or any symptoms whatsoever. We have saved hundreds from damage & failure from contamination.

    We have, however, seen hundreds of Common Rail pumps fail due to fuel contamination where no additional fuel filter has been fitted. Enough said.

  • Does the addition of another fuel filter restrict the flow of fuel?

    Some unsuitable aftermarket filters may present a flow problem but the Fuel Manager FM100 has more than adequate capacity for all 4WD & SUV diesels available today. The Fuel Manager FM100 is designed for use on common rail fuel systems.

    The flow rate of the filter assembly with a 2 micron filter is rated at 300 Litres per hour and suitable for engines up to 350hp.

    Diesel Care has conducted testing & trials over many years to ensure that our kits don’t cause any problems with regards to fuel supply. We have sold tens of thousands of our kits & have had no reported symptoms of fuel restriction causing loss of performance. If there was any problem in this regard we simply wouldn’t fit them.

    See our tests here.

  • What should I do if the Fuel Filter warning light on the dash comes on?

    The filter warning light is to alert you that there has been water detected in the sedimenter part of the filter assembly, & in some vehicles it can also warn of a filter that’s becoming blocked, e.g. Toyota has this restriction warning feature.

    Whatever the cause, a filter warning light should not be ignored. You should stop & investigate at the first possible opportunity. The first thing to do is drain off some fuel from the filter drain cock. This is positioned at the base of the fuel filter assembly & because water is more dense than diesel, it will be the first liquid to come out.

    It’s a good idea to catch what you drain into a receptacle so you can see if water is present, if there is, the warning light should go out once you’ve re-started. This instance of water in the fuel is where a Diesel Care Secondary Filter Kit really pays for itself. i.e. if any water has managed to get past the factory filter it will have been caught in the secondary filter.

    If any water has been evident its best to replace the filters. Filters are cheap, water damage is expensive.

  • Where can I buy a replacement filter cartridge?

    Replacement cartridges can be purchased from quality Diesel Injection repair shops by quoting the part number on the filter. By quoting the part number you will be sure to fit the correct filter to your particular vehicle.

    Filters vary in Micron rating and size, so it’s important to get the right one. We can mail you one if you don’t have an outlet near you, just call 1800 880 150 or purchase online from our diesel-store.

  • How often should the filter be changed?

    This depends on which Filter Kit you chose; Primary or Secondary.

    Primary filters need changing more often than Secondary because they are filtering fuel straight from the tank, whereas Secondary filters don’t need to be changed very often because they are filtering fuel that’s been through the factory filter. So this is the general rule:

    • For Primary filters we recommend you replace the cartridge every 20,000kms.
    • For Secondary filters we recommend you replace the cartridge every 40,000kms, or every second time you change your factory filter, whichever comes first.

    The exception to the above rule would be if you encountered contaminated fuel, in which case you should change the filters early.

  • Could secondary fuel filter systems cause problems to fuel flow?

    Some rotary fuel pumps are very sensitive to restriction (Bosch VP44, Denso ECD-3 & ECD-V4).  So in instances like this we recommend a primary filtration at 30 micron as the only option.

    But most high pressure systems these days including Common Rail are intolerant of contamination & their repair costs are high.

    Secondary (final) filtration at 2 to 5 micron is the best thing you could do to increase the life of your fuel system & safeguard against expensive repairs due to fuel contamination.

  • Is an additional fuel filter difficult to install?

    We have spent many hours developing our products, testing, manufacturing and testing again to ensure that our kits are suitable for the DIY’er. Naturally; some basic skills, some mechanical aptitude, & hand tools are required, along with good old fashioned common sense.

    We try to make our instructions as easy to follow & as clear as we can. Even so, if you get stuck with some minor technicality we are happy to help you out over the phone. Our Techs fit our kits all the time & know all the ins & outs so help isn’t far away.

  • Will installing an additional filter kit avoid the vehicle warranty?

    Installing a water separator filter kit will not affect warranty as it works in conjunction with the original filter. It does not replace the original filter. There may be some reluctance by some vehicle Dealerships to alter the vehicle from standard but we supply our filter kits to a number of dealerships around the country.

    The fact is; if you get contamination in your fuel system; there is no warranty. We recommend you discuss installing an additional filter with your Service Manager, & explore the “what if’s” with regards to fuel contamination damage to your vehicle.

    A Service Manager with common sense will see that you are far less likely to incur expense with a Diesel Care kit fitted.

  • Are secondary filters connected before the OEM filter to avoid warranty issues?

    The secondary filters are fitted after the factory filter, Pre filters are before. We use coarse filtration for Pre (30 micron), much finer filtration for Secondary (2 micron). There should be no problem with warranty as we are not removing the factory filter.

    We supply both Pre & Secondary configurations to a number of vehicle dealers around the country.

  • Is the secondary kit compatible with the flow rate of a 2010 Toyota Prado GXL engine?

    Yes the kit is compatible with the flow rate. The fuel managers are designed for common rail systems. The flow rate on the filter assembly we use with a 2 micron filter is rated at 300 Litres per hour and up to 350hp.

  • Do you deliver the filter kits to PO Boxes?

    Yes, the filter kits are sent out in express post bags so they can be sent to a PO Box.

  • Do you accept direct deposit for items purchased through the Diesel Store?

    Yes we do take direct deposit. Please contact us and we will supply our bank details.

  • Does the kit include an extra filter?

    No, only one filter  cartridge comes with the kit however, extra filters can be supplied at an additional cost and can be purchased through our web store or by phoning us on 1800 880 150.

  • There are 2 types available, what’s the difference?

    There are two variants for most of the vehicle range we cover; Primary (pre) and Secondary (final).

    In short, Primary filters are plumbed before the factory filter and is a relatively course filter rated at 30 microns.

    Secondary filters are plumbed after the factory installed filter and is rated at 2 micron or 5 micron, depending on the vehicle.

    Read more detailed information on the differences and what we recommend here.

  • How do you inspect and change a fuel filter?

    The team at our Dalby branch have put together a short video showing the process on how to check your secondary fuel filter for contamination and demonstrate how simple it is to change.

    Watch this video to see how it’s done! An instruction sheet is also provided to download here for you to use.

  • Is the filter easy to replace and maintain?

    Notwithstanding the congestion in the engine bay which can make access to filter a bit awkward on some vehicles, the filter cartridge is easy to remove when it’s time to change it.

    In fact it can be removed without the need for hand tools thanks to the cartridge retaining nut which can be loosened by hand. Another great feature of the Fuel Manager is that the cartridge can be removed without creating a fuel spill, thanks to the enclosed top on the cartridge.

    This great design also extends to the rubber seals being an integral part of the cartridge so you don’t have to worry about replacing fiddly O rings or gaskets.

  • Does your filtration kit fit when there is a dual battery system in place?

    Yes, they do fit with a dual battery system fitted in the majority of applications. There are a few exceptions but we do our best to design a kit that fits with commonly fitted under bonnet accessories.

    We offer a couple of different mounting positions for some vehicles to try & address commonly found space challenges.

  • Why fit an additional fuel filter when there is already a factory filter installed?

    You might think that the fuel filter fitted to your car by the manufacturer is adequate protection. Sadly, the truth is often they are not.

    The very reason we started developing our filter kits in the first place was because we regularly see damage to diesel pumps & injectors from contamination penetrating the factory fuel filter.

    The damage can be catastrophic & expensive so the best defence is to add an auxiliary filter to clean the fuel better & more thoroughly.

  • There are other fuel filter kits out there on the market how is yours different?

    • Our kits are the original kits. Our brackets are designed & developed by Diesel Care’s experienced technicians & are all made in Australia using high quality stainless steel. Our bracket designs are so good they are copied, but they are never equalled.

    • The Fuel Manger Filter included in the kit is made in the USA and is recognised as one of the highest quality fuel filter systems on the market.

    • Diesel Care kits have been developed as both Primary & Secondary options. None of the copy-cats offer both.

    • Because we develop the kits, we have the largest range available.

    • Expert advice is only a phone call away. Our Technicians are happy to offer advice with the installation or answer any questions you may have.

    • Everything is included in the kit to do the job yourself but if you’re pushed for time or just don’t feel like tackling the job, book into one of our stores and we can fit it for you.

Johnnos Camper Trailers

  • Why does Australian made matter for the canvas on the trailer?

    While camper trailers at face value look very similar they can be vastly different in quality. Australian made canvas will generally of the highest possible quality and have inbuilt mould retardant in the manufacturing process to suit Australian conditions.

    To save on costs many non-guild members use cheaper overseas manufactured canvas that looks fine, until it rains.

    This recent CSIRO analysis of imported 14 ounce “ripstop” canvas shows the difference: See the report here

    The canvas leaks water when it rains, when you pack up and drive home mildew will form on it, making it necessary to replace the canvas in some instances: Ripstop Fabric problems

  • How do I identify if its Aussie canvas on the Camper trailer?

    Aussie made canvas will have a “Care” label on it that identifies the manufacturer of the canvas.

    If you can’t locate it on the canvas tent or the care label does not identify the canvas as Australian Made it almost certainly is not.

  • What is the most important component in a camper trailer?

    The canvas tent.

  • Why is the canvas tent the most important component?

    If it leaks or has condensation or mildew problems a holiday can be ruined and the camper is not fit for the purpose.

  • How do I know if the canvas is fit for the purpose?

    It should comply to the Australian standard for canvas AS 2001.2.18.1987 which is also the military standard.

  • How do I know if the canvas meets this standard?

    Australian canvas manufactured by Wax Converters (dynaproofed) meets this standard.

  • Why does Johnno’s use the Hyland hitch?

    There are several different types of hitch in common use for off road camper trailers.

    We use the Hyland hitch because it is very reliable, strong and very easy to hook up with the 50mm ball compared to the poly block type that uses a skinny pin which can be very difficult to insert when in off road conditions.

  • Why does Johnno’s use the chunky off road tyres on the off road camper trailers?

    These tyres are very tough and we rarely have punctures due to the heavy side wall construction.

  • Are the Johnno’s Camper Trailers made in Australia?

    Yep, sure are. They are made in the only purpose built camper trailer manufacturing facility in Australia.

  • What is the big deal about the canvas being Australian made?

    Australia has more Ultra Violet light content in its sunlight than most other countries.

    UV light is potentially very destructive on canvas, affecting the water proofness of the material.

    Our canvas is made to the stringent Australian standard which is a lot tougher than the international standards.

    Australian canvas is tough and is waterproof yet ‘breaths’.

  • Can I buy a Sleepout or even the awning walls later when I am in a better financial position?

    Yes, our Sleepout and awning walls will fit any camper trailer tent made after 2012 and are always available through your local Johnno’s Outlet.

  • What about rust proofing?

    Johnno’s camper trailers use Duragal plated draw bars and Zincaneal panels.

    These treatments are permanent plating techniques this means the camper trailer is protected from rust by the very nature of the materials used.

  • I understand Johnno’s use electric brakes on their trailers. Do I need to have a brake controller in the vehicle?

    You will need an electric brake controller fitted to your vehicle.

    Brake controllers should be fitted by a qualified mechanic and are not particularly expensive.

  • What about re-charging the on-board battery?

    There are several ways to re-charge the battery fitted to the camper trailer. The easiest method is to use a conventional mains power battery charger at home.

    Alternately, with extra equipment mounted in the camper trailer and the tow vehicle, you can re-charge the camper trailer battery from the tow vehicle whilst you drive.

    See your local Johnno’s dealer for more details.

  • Can I cook with the awning set up? Doesn’t the kitchen end wall get splashed?

    Cooking underneath the awning is fine as the awning is quite high.

    The kitchen end wall is pegged out, drawing it away from the kitchen.

    We haven’t had any issue with the wall getting splashed whilst cooking, but the area behind the kitchen is made from heavy duty pvc, so it can be easily wiped down if need be.

  • Is it safe to cook with the entire annex set up?

    Safety regulations advise that you shouldn’t cook with gas without adequate ventilation.

    When the awning is enclosed with the annex wall kit, ensure adequate ventilation when cooking by opening windows or removing a panel of the wall kit.

  • How easy is a Johnno’s Camper to set-up?

    We have spoken to a few different people and they tell us a hard floor camper trailer is a lot easier to set up than a soft floor camper trailer?

    Well.. a Johnno’s Camper is extremely user friendly and why our Campers are so well known in the Soft Floor camper trailer sales & hire industry.

    For a quick over-night stop it will only take you a couple of minutes to pull out your main tent. For longer stops, you then may want to extend the camper awning for more living space and we can completely set up our campsite in around 15mins.

    So, in our opinion, a Johnno’s soft floor is definitely comparable to a hard floor camper in relation to quick set up time IF NOT faster than a lot of models!

    I certainly wouldn’t rule out a soft floor camper from your short list because you think it might be difficult to set up!

  • Why is an Australian Built Camper Trailer more expensive than imported brands ?

    Bottom line‚ you get what you pay for.

    Johnno’s Campers are a fully Australian Made Camper Trailer, purpose built‚ for our conditions with Australian Made Products and built by Australians right here.

    Our long heritage in the hire & sales industry ensures that our customers are buying a tried and tested product used by Australians all over Australia, all times of the year in all different types of terrain and weather conditions.

    WE are also part of the AMCTG which gives our customers even more reassurance when buying a camper trailer.

    And not to forget, Johnno’s are part of the biggest Camper Trailer Network in Australia.

    Your guarantee that you are part of product that spans the whole country to provide you with after sales service and advice and not to mention, peace of mind! Can you get that from an inferior imported product?

  • Where is your canvas made and is it Australian?

    Our canvas is made at Wax Converters Textile Company in Maitland NSW and yes it is all Australian.

  • How do you clean the tent?

    Clean water and a sponge, even use a chamois to draw the water out.

  • Can you pack up a tent when it’s wet?

    Yes, but don’t leave it closed and wet for any longer than two days otherwise the tent will get mould on it.

  • Is the canvas “Rip Stop” – imported from China?

    No we only use Australian canvas from wax converters, who are Australia’s biggest canvas supplier.

  • Is the canvas see through when a light is turned on internally?

    No , as we only use the best quality Australian canvas , you can have an internal light on and be confident that there will be no external shadows of you inside.

  • Is the tonneau cover canvas or vinyl?

    The Tonneau Cover is made of The Stealth Ripstop’s advanced construction and is based on superior chemistry and technology. It is specifically designed as a hard wearing Tonneau Cover for many marine and automotive applications.

    The fabric possesses many exceptional benefits including tear, tensile and bond strength, UV and abrasion resistance.
