The feed line is 5/16" (going to fuel filter) and the return line is 1/4" (coming from factory FPR). From your picture, I want to say you placed that fitting on the return line which is 1/4" I was contemplating putting that 5/16" fitting on it because the return line PSI is already low enough.

im going to check 2 marrow becuse when i first tried to put it on the feed line did not seem to fit might need to sand it down after i cut it. the return line seemed a little loose but looked like it would be alright after i fully tightened it. the part im using is # 165056 from http://www.anplumbing.com/shop

AN plumbing rocks. 165056 will only (technically) work for the 5/16" feed line. If it ends up working for you on the 1/4" return line, let me know, Ill use that fitting instead of buying a 37 degree flare tool. :up:
