I heard Fram filters cause a big restriction??


IMO Fram fuel filters are junk.




Point of reference. My Mallory 140 sucked 1 gallon in 25 seconds through my OLD Fram and 1/2" lines. That's free-flow to the regulator. I changed to a stated 500gpm stainless mesh canister filter and it flowed exactly the same.
It ran 10.39@128 on E53 last night but was a little rich on that run with 94/95 jets.
