Auxiliary Fuel Filters

Auxiliary Fuel Filters Overview

When fitted to late model CRD vehicles, Auxiliary Fuel Filters can save you $1000’s of repairs and inconvenience. Australia now uses Ultra Low Sulphur Fuel. ULSD is more susceptible to water emulsification – water molecules suspended in diesel. This is more difficult to remove than in traditional diesel fuel and is the reason why old technology sedimenters work relatively well removing whole water, but struggle with emulsified water, the contaminant you can’t see that does all the damage.

How do you know if your vehicle has water / particle contamination?

  • Loss of RPM / power
  • Blows excessive smoke
  • Has a foul odour
  • Shudders and shakes at all speeds
  • Suddenly stops while driving / hard to start

It’s easy to think that fuel contamination is something that happens “in the bush” but this is simply not true! 72% of all diesel fuel injection system failures are caused by water and fuel lubricity problems? That’s because water vapour condensation in the fuel tank is a constant source of water in diesel. Direction Plus™ Fuel Manager Pre-Filter Kits protect late model common rail diesel engines against costly pump and injector failure.

Installing a Direction Plus™ Fuel Manager Pre-filter kit between the fuel tank and the O.E.M fuel filter will remove the majority of water and particle contamination from the injection system – the pump, the ‘common rail’, and the injectors. Water entering the fuel system displaces the lubricating diesel oil, resulting in rapid wear of the pump, but more importantly, the injectors. Injectors move upto 8 times per firing stroke, so that’s 100’s of movements every minute.

CRD injectors cost in the vicinity of $2500 to replace on four cylinder models, nearly double that on the Landcruiser 4.5Li V8 TDi, hence it is well worth spending a few $100’s on prevention.

The O.E.M fuel filter will do the final and finer filtration. This ensures you are maximising the protection of your diesel fuel system.

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

Benefits of a fuel manager pre-filter kit

• 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
