  • fuel manager final filter 2 micron

the first line of defence Against Particle Contamination

Did you know that poor quality fuel or contaminated fuel can cause failure of the injection system and damage the diesel engine of your vehicle?

Contaminated fuel can have germs, water, or particles inside jerry cans and even from service stations.

Repairing the damage caused by fuel contamination in an engine can cost more than $10,000!!!


To ensure that you get the best protection, we recommend installing Direction Plus Fuel Manager Post-Filter Kit to protect late model common rail diesel engines against particle contamination and injector failure.

All common-rail systems have one factory filter. Installing Direction Plus Fuel Manager Post-Filter kit between the engine and the O.E.M fuel filter, will remove any contamination not captured by the O.E.M fuel filter ensuring you are maximising the protection of your diesel fuel system against particle contamination.

For the first line defense against particle contamination, invest in a Direction Plus Fuel Manager Post-Filter Kit and protect your investment 24 hours a day, 365 days a year.

POST-filter important?

The Direction-Plus Fuel Manager Post-Filter kits are designed specifically to cope with extreme weather conditions and poor diesel fuel quality.
