Direction Plus


Protect your Diesel fuel system against failure and expensive repairs from water and particle contamination with the Direction Plus Pre-Filter Kit.


Direction Plus™ Diesel Fuel Pre-Filter Kits protect late model common rail diesel engines against costly injector failure.


Installing a Direction Plus™ Pre-Fuel Filter kit between the fuel tank and the O.E.M. fuel filter will remove the majority of water and particle contamination.  This leaves the O.E.M. fuel filter to do the final and finer filtration and ensures you are maximising the protection of your diesel fuel injection system.


Designed specifically to cope with our extreme weather conditions and poor fuel quality, they are the perfect choice for drivers in Australia.  No matter if driving in high humidity, dry cool climates, or frosty conditions the Direction Plus™ Diesel Fuel Pre-Filter kit will remove water and other contaminants from our Ultra Low Sulphur Diesel (ULSD).


ULSD is more susceptible to water emulsification, that is water molecules suspended in diesel which is harder to remove than in traditional diesel fuel.  This is why old technology like sedimenters work relatively well removing whole water, but struggle with emulsified water, the contaminant you can’t see.


For the ultimate front line defence against water and particle contamination, investing in a Direction Plus™ Diesel Fuel Pre-Filter Kit will protect your investment 24 hours a day, 365 days a year.


Reduce wear & tear and avoid repair costs that can exceed $10,000

95% water separation and superior particle removal

Ability to separate emulsified water from ULSD

Clear water drainage bowl to easily identify removed water

Keeps critical engine components clean

No filter bypass – contaminated fuel will not be sent to the fuel system even when the filter is blocked


The first line of defence for your engine’s intake system.

Protection against costly repairs and poor performance.


Direction Plus™ ProVent® oil separator kits protect your modern diesel engine by substantially reducing the amount of oil entering the engine from blow-by gas in the crankcase ventilation system.


The problem is compounded by modern engine fitted with exhaust gas recirculation systems (EGR) whereby a proportion of the exhaust gas is routed back into the engine.  With the presence of oil from the crankcase ventilation system, the exhaust particles are collected by the oil.  The combination of oil and exhaust particles from the EGR build up to a point where it blocks inlet manifolds and valves, resulting in reduced engine performance and/or failure.


By not fitting a Direction Plus™ ProVent® system, it is likely that your engine will experience a progressive reduction in performance.  These images are typical examples of the buildup in engines not fitted with an oil catch can system.

Direction Plus™ ProVent® systems, are specifically designed to separate and redirect oil and air from blow-by gas produced from within the crank case.  This oil separator system also provides the option of returning the oil back to the sump.


Prevents oil and soot contamination entering the clean air intake

Excellent protection for turbocharger

Minimises oil consumption (Only in installations where the oil is returned to the sump)

Prevents oil buildup in intercoolers

Regulates crankcase pressure

Keeps critical engine components clean

Reduces exhaust smoke and odours

Saves you money
