One of our customers has a FASS Titanium® fuel system on his 2012 Dodge 3500 with a 6.7 Cummins. He is in the hotshot business so a lot of fuel flows through those injectors in a year's time and clean fuel is a must when your truck is your livelyhood.

Even if you do not earn your living with your truck, I will go out on a limb and say that it is wiser to keep those "new injector" dollars in your pocket than send them to the manufacturer of fuel injectors.

The owner of the truck asked us to cross his FASS fuel filters over to a high quality filter that he could purchase through his AMSOIL wholesale account. To make it easy he provided us with a page (page-18) from his FASS Titanium Series manual.

We received the FASS information in September of 2014 and put together some information that actually ended up saving the customer some money while providing high quality Donaldson fuel filters and fuel/water filters as replacements for his original FASS filters.

DISCLAIMER: We compiled this information from the FASS manual and the Donaldson website in September of 2014 and it was accurate at that time. Make sure that these filters are suitable substitutes for your installation before you purchase.
