Ok, so I searched around the forums and I couldn't find anything that helped, so here's my issue. . . I just recently rebuild my 1996 3.8 v6 due to a blown head gasket, and got all the finishing touches done today. But when I was pulling into the shop to get my exhaust welded up again, the mechanic noticed a HUGE fuel leak coming from the engine bay. So we relieved the fuel pressure, doused the engine with water, and they did their business. After the exhaust job was done (headers to dual 14" glass packs ) I pulled it into the parking lot and popped the hood. It seems like the Fuel Pressure Regulator is leaking gas all over the engine. I unplugged the vacuum line and it is creating vacuum just fine. I removed it and the 2 o-rings look fine, so I tightened it back on only to have it just leak again. Oh, and it seems like that when the vacuum line is connected, and you shut off the car (and maybe when the car is running also, its hard to tell) that there is a hissing sound, kind of like a vacuum leak. If I was a rich man, I would just go buy a new $79 regulator from NAPA, but I've got about $40 in my pocket and i want to make sure thats what I need to do before I do it. thanks guys!
