I've been wrestling with the problem of replacing my (incorrect) fuel pump on my 427/425 car for a couple of weeks now. The problem involves adapting the inverted flare female outlet on the pump to the vertical fuel output line to the Y block before the bowl feeds. I was unable to find ANYWHERE, and believe me I searched all the parts stores including NAPA and also the internet for a fitting adapter which will adapt the inverted flare female to a 90 degree inverted flare male which would accept the supply pipe.. So, after sending one correct pump back to Paragon (who had no fitting adapters, I thought Long Island Corvette had the answer. It cam in today and their adapter uses a straight pipe fitting with a rubber washer which fits inside the inverted flare, but the female end of the fitting is for 1/4" straight pipe, not 1/4" NPT pipe thread which will accept my inverted flare female elbow. My elbow will only thread into this adapter 1/2 turn, which I would really be nervous about driving around with. DOES ANYONE HAVE A PHOTO OR CAN DESCRIBE WHAT KIND OF OUTPUT FITTING AN ORIGINAL 427/425 FUEL PUMP LOOKS LIKE? Could be that my elbow is incorrect.
Long Island's repo pump and fitting, my elbow with 1/4" NPT pipe thread The fitting is straight pipe, not NPT and has a washer inside to seal up against the inverted flare! My elbow screws in about 1/2 turn, 180 degrees max and maybe two threads. Not enough of course.
I'm down down to repairing and reinstalling my (incorrect small block pump with allen head studs to prevent the pivot pin from walking out which is what happened and caused me to attempt to replace it with the CORRECT reproduction pump. I should add that it ran great with the 327 pump.
Any ideas? Similar experiences?
