Can someone please tell me what thread and pitch the quick-connect fitting is that threads into the inlet side of the 1st gen diaphragm pump? I'm trying to get my fittings ordered for a 2nd gen piston pump install with a boost referenced bypass regulator. I want to use my factory fuel feed line as the bypass regulator return (I'm going to 1/2 draw straw) and if I can figure out that fitting, I can adapt it to my regulator return. Thanks for the help all!
