How much pressure drop is acceptable from the Pre-OEM fuel filter ?


What are the implications ?


Can we use depth type filtration instead of pleated paper filtration ?

from what i've been told spec is 3-8 InHg measured at teh test port @ idle. i couldn't tell a difference w/ the CAT filter. i checked it a few times and once or twice noticed 1/4" InHg difference.. so i would think as long as you stay within spec you are just fine.
