Cornell Diesel System’s Fuel Manager Diesel Filter Kits

Fuel Manager Diesel Filter Kits


Modern diesel engines are equipped with advanced high-pressure injection systems that can be easily damaged by poor quality fuel or, more frequently, contaminated fuel.

Common Rail (CR) diesel systems can run up to 40,000 psi. Many of these systems are intolerant to water and dirt particles and, if contaminated, result in costly engine repairs.

One way to provide better protection for your diesel engine is to install an additional fuel filter and water separator. Most CR systems only have one factory filter, so installing the additional filter is highly recommended, if not essential. Fuel Manager manufacture several options to meet each vehicle’s requirement.

Primary (Pre) Filter – 30 Micron


Plumbed before your factory fuel filter and rated at 30 microns, the Primary (Pre) Filter prolongs the service life of your factory OEM filter. A 30-micron filter will remove particles the size of 30 x 1000ths of a millimeter. This may sound very small, and it is, but not small enough to protect modern high-pressure CR fuel systems. Most factory filters on modern CR systems are rated at 10 micron.

Secondary (Final) Filter – 2 and 5 microns

Plumbed after the factory filter as a last line of defence, the secondary filter in both 2 and 5 microns will effectively remove any water or contaminates that make it past your factory filter. A 2-micron final filter will remove particles the size of just 2 x 1000th of a millimeter.


We stock a full range of fuel filter kits (including Hilux as shown for illustration only) designed specifically for easy install, to save you time and money. If you require more information please contact our friendly staff on 03 9267 8800

HPD Catch Can

HPD Catch Cans

The HPD Catch Can is one of the simplest and most effective accessories you can fit to a turbo-diesel engine.

To meet ever stricter emissions regulations, manufacturers of diesel engines have used Exhaust Gas Recirculation (EGR), which diverts sooty exhaust gases back into the engine to be burned again, reducing particulate emissions.

The engine breather pipe sends air from inside the crankcase into the intake as well. The fine oil mist in this air combines with the soot from EGR to form a sticky deposit that builds up to the point that it affects the breathing of the engine, clogs EGR valves and jams turbo actuator flaps.

HPD has tackled this problem with a catch can that filters out damaging oil mist and condensation from the air entering the inlet passage. The HPD catch can does not vent to the atmosphere, so it’s compliant with Australian Design Rules and Standards.

The oil reservoir has a dipstick for easy monitoring of the oil level, and unscrews for easy emptying when required. The mesh filters require little maintenance – only occasional cleaning – so you don’t need to spend money replenishing filters.

Designed and manufactured in Australia from billet aluminium, HPD catch can kits come complete with laser cut brackets, silicon hoses, and all clamps and fasteners needed to complete a factory look fitment.

Benefits of using a Catch Can

  • Maintains vehicle performance, power and efficiency
  • Reduces carbon and oil build up in the inlet manifold
  • Stops oily residue build up in the intercooler
  • Ensures clean air is delivered to the engine
  • Protects turbo bearings from corrosion

Advantages of fitting a HPD Catch Can

  • Dipstick to check oil level
  • Washable filter (no need to replace)
  • 360° rotating inlet to assist fitment
  • Universal stainless steel fitment bracket
  • Easy step-by-step fitment guide
  • 100% Australian made and engineered

Diesel Particulate Filters

What is a DPF (Diesel Particulate Filter)?

A DPF is used in diesel vehicles that comply with Euro-6 emission standards. The manufacturers use the DPF to filter, store and burn the soot particles that are emitted as a result of the combustion process of the diesel engine. DPF’s come in a common cylindrical unit. The DPF consists of silicon carbide. It can filter about 99% of solid particulate matter from the exhaust of a diesel engine. The soot particles or the carbon particles deposit on the filter channels are oxidised into carbon dioxide at exhaust temperatures above 600degC. Basic DPF’s are the single use type. You need to dispose or replace them when they get full, after accumulating ash and when regeneration is no longer possible.


What are Particulates?

Particulates are a form of carbon that accumulates in the exhaust system of the vehicle’s engine, originating from various leftovers that define what type they are. In term of vehicles, particulates are the minute solid particles of exhaust gases emitted from the engine. The engine emits these particulates mainly in the form of carbon or soot. The particulate matter forms a layer of carbon inside the exhaust system of the engine. This is the main reason why taking care of the exhaust system of the engine is so important. It is necessary to limit the quantity of emitted carbon particulates to prevent environmental pollution.


How does a DPF work?

The unfiltered exhaust flows through the DPF’S channels that open at the inlet end. The core contains porous walls of a ceramic honeycomb structure made of silicon carbide. The exhaust gases then enter into the channels that are open at the outlet end. The exhaust system takes away the exhaust gases. The DPF core retains the soot particles and later burns them off during the regeneration process. The ECU computes the amount of soot and ash accumulation in the DPF with the help of the DPF differential pressure sensor.


Components of a DPF

The temperature sensor upstream of the DPF detects the temperature of the exhaust before it enters the DPF. The integral resistor changes its electrical resistance according to the exhaust temperature and then sends a corresponding voltage signal to the ECU control unit. The control unit uses the voltage signal to monitor the rise in exhaust temperature before and during the regeneration process. The DPF differential pressure sensor detects the difference between the exhaust upstream and downstream of the DPF. The exhaust pressure sampling pipes – upstream and downstream of the DPF – detect the exhaust pressure difference. The pressure difference between the exhaust pressures upstream and downstream of the DPF acts on the piezo electric pressure sensor element. This produces a voltage which is passed into the ECU as a voltage signal.


What is Regeneration?

Regeneration is the process that burns off the soot particles accumulated in the DPF as C02. The regeneration takes place when the ECU detects a certain pressure difference in the DPF, then at a certain speed usually above 80kph the DPF temperatures will raise to about 600 degrees Celsius, causing the soot build up to burn away. This will continue until the pressures in the DPF fall back into specification. That is why it is recommended that a vehicle with a DPF be driven on a freeway at least 20 minutes every week to initiate a regeneration (please consult vehicle owner’s handbook).

Variable Nozzle Turbine (VNT) diesel turbo

Problems with Variable Nozzle Turbine (VNT) Turbos

Since the late 1990s many diesel vehicles have a Variable Geometry Turbine (VGT) or Variable Nozzle Turbine (VNT) turbo fitted. These turbos minimise turbo lag, improve throttle response at low speed and provide much improved torque.

Most commonly, the design utilises a ring of moveable vanes around the turbine wheel to change the speed and direction of the exhaust gases acting on the turbine wheel. At low speeds the vanes move closer together which accelerates the gas flow onto the turbine wheel. At higher speeds the vanes open wider to prevent the turbo over boosting.


Despite these benefits, turbos can be prone to problems, which include:

What to do when you put petrol in your diesel vehicle

Driving comes with many risks, but the simple task of fuelling up isn’t risk-free either. If you’ve ever put petrol in your diesel vehicle, you’re not alone in making that mistake. According to the Royal Automobile Association of South Australia (RAA), 7500 misfuelling events, of people doing just that, occur every year nationally. This mistake could cost you your engine if you don’t deal with it properly, however, there are actions you can take to minimise the cost of repairs.


Why you should consider diesel

The Petrol Vs Diesel debate is a never-ending one. No matter where you stand, there is truthfully no clear winner. Your champion will depend on what you need your car for and what you want from your vehicle. Do you want a vehicle to help you run quick errands? Or, do you want to go on long drives dragging a trailer behind you? Each engine type has unique benefits, but many do not realise how diesel could better cater to their needs.


Diesel vehicles are more fuel efficient and emit less CO2 than petrol engines which is better for the environment. Efficiency will vary from vehicle to vehicle, but owners can generally expect fuel efficiency to be 24 to 30 per cent better than petrol equivalents. Diesel engines have more compression, so the expansion part of the cycle occurs over a greater range, delivering more usable power and better economy. Ultimately, this means that diesel vehicles have to refuel less.


Diesel engines operate at higher pressures when compared to petrol engines. This means that structurally, the engine needs to be significantly stronger. Their hardiness makes them ideal for drivers covering rough terrain, particularly off-road. This strength also means better longevity and dependability.

Torque and power

Recent additions to the diesel market have developed diesel engines that are more powerful and responsive than ever – and many now outperform their petrol-powered equivalents. Diesel engines deliver substantially greater low-speed torque at about 2000rpm at three or four times the torque of a petrol engine. Diesel vehicles are therefore better-performing on the freeway as they provide strong overtaking agility and can often do so without changing gears; they can scale hills effortlessly, are ideal for towing, and generally move without complaint. For those who regularly tow caravans, boats, trailers, general heavier loads or carry more people than average, diesel is the better choice.


The distinctive ‘rattle’ generated by large diesel engines have been virtually eliminated in most modern passenger vehicles. When the engines are cold and near idle, they can sometimes generate more noise than a petrol engine. But at suburban or highway speeds, diesel engines are mostly quieter and smoother than ever.

In the end, you need to think about what you want to use your car for and what you want it to do. Diesel may not be the perfect fit for everyone, but they are a fantastic choice for the drivers who cover long distances, venture off-road frequently or want superior torque.

Top 5 DIY tips to Maintain your Diesel Engine

Regular maintenance is essential to ensuring the longevity of your diesel engine. If you have a diesel vehicle that you often use for transporting loads, then there are a few maintenance tips you can be following to ensure your vehicle remains effective. The typical maintenance tasks include changing the diesel oil, inspecting the filters, checking the engine’s coolant, draining the water separators, and taking care of your turbocharger.

Diesel Oil Changes

As diesel engines are high heat running motors, diesel oil changes are critical. By checking and changing the oil, the engines will continue to work efficiently and smoothly. If the oil is not replaced it will block the heat transfer and hamper the oil’s cooling function. Oil changes are recommended every 6 months or 10,000 km. However, if you use your vehicle for hard-driving and towing then it becomes necessary to change oil more frequently.

Inspect your Filters

Inspecting and replacing diesel fuel filters is crucial to the welfare of your vehicle. It is usually located within the engine bay. With today’s diesel fuels the filters need to be changed at certain intervals. It should be a priority to change the oil filter each time the oil is changed.

The air filter is one of the areas of a car that can accumulate the most dirt due to the engine. If you don’t keep it in good condition, you run the risk of poor performance and it increases your fuel consumption. Air filters need to be changed every 10,000 km to 15,000 km or every 12 to 18 months (depending on conditions).

Check Your Engine’s Coolant

Engine coolant maintenance is equally as important as an oil change, and more than 40% of diesel engine maintenance problems can be attributed to engine coolant negligence. An engine’s cooling system runs off coolant, which is a mixture of water and coolant additive. However, the coolant can often become acidic over time and can cause major problems. It is important to replace the coolant filter and top off the cooling system at every oil change, test the coolant twice a year, and replace the coolant every two years. Plus, make sure the coolant you are running in your engine meets the original equipment’s manufacturer specifications.

Draining the Water Separators

One of the important reasons to drain water and dirt from a diesel engine is that diesel fuel becomes contaminated easier than gasoline. This can cause corrosion in the fuel delivery system. To avoid this, many diesel cars install a water separator. This small filtering device is used to remove the water from the diesel fuel before it reaches the sensitive parts of the engine.

Save your Turbocharger from Failing

A lot of things happen in a matter of seconds when you turn on your car, and one of the most crucial ones is the flow of oil coming from the oil pump to the turbocharger. You should always allow your vehicle to start up and idle for a few minutes before departure. In this way, the engine oil has time to reach the turbocharger. So, the worst thing you could do to a cold engine is mashing the accelerator as soon as you start your car.
