    Hi all. I just installed CFM-tech's fuel pressure gage. Now I can't get rid of a leak where the stock fuel inlet line screwes into the CFM tech adapter (the piece that the gage mounts into). I tried original o-ring (it looked good)... small leak. I tried new o-ring... small leak. I tried progressively tightening the line in small incraments... small leak every time.

    I just picked up the replacement o-rings at AutoZone... multipack fuel injection o-rings... and tried using the one that matched stock.

    The inlet line looks good (double bump flare intact).

    Any ideas?
