Hi all. I asked about this in the garage... but I thought maybe it was better here... I just installed CFM-tech's fuel pressure gage. I now have 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). Anybody else have this problem??? Any ideas?
