Fuel Effiecent C15 Fuel Filters?

I read on another forum that using a Fleet guard fs 1212 filter will improve fuel flow. Anyone know of a better filter with a higher flow rate? I am installing F.A.S.S. later this year.

Answer this question I have this problem too

Is this a good question?

Does this replace the primary or the final filter ((before the transfer pump,or after ?) If it's after the fuel pump be very careful about the micron numbers ! Cats require a 2 micron fuel filter,anything less(larger number) will void any Cat warranty on the fuel injectors ! Yellow filters for yellow motors is the safest policy !

It will on a CUMMINS N14. Fleetguard FS1212 flows better but was replaced by FS1001 (IIRC) because the dirt it was letting through was killing injectors. Does your CAT take the same filters?

FASS will do nothing for the flow past the fuel pump as it only pressurizes fuel before it goes into the pump. The fuel pump regulates the fuel pressure to the injectors.

I agree with "Yellow Filters on Yellow Engines"

Cat researched an injector trashing problem on earth moving equipment. They dismantled injectors to show the wear patterns in critical moving parts and without using the lower micron rated Cat filters, the injectors simply wore out due to the close tolerances. I have also read that truck engines require a finer micron rating then say earth moving equipment, maybe because of ACERT technology?, so be sure and get the factory called for filters. Also, an ACERT will derate on a hard pull if filters are too stopped up.
