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. This ensures you are maximizing the protection of your diesel fuel system.
