Hey Guy's. just purchased a Carter Mechanical Fuel Pump For 340 It has 1/4 NPT female inlet/outlets. also purchased aeromotive 1/4 NPT to 8AN adapter fittings. I get MAYBE 2 threads screwed in before hand tight, & cant imagine getting much more with tightening allthough I have not tried yet for fear of breaking pump housing or fitting.instructions also state, NOT to use Teflon tape, so to me that would mean fittings would need to be seated pretty good for chance of no leak. what are your thoughts? Thank you
