Gentlemen, I purchased 796/1000 several months ago (completely stock). The previous owner replaced the faulty fuel pump sending unit with a brand new OEM unit (and spent an arm and a leg for it). In doing so he ct the stock rubber hose and stripped one of the studs the bolt the sending unit to the tank.
Currently, I get a strong gas smell, the is stronger in the back seat than in the front seat. It gets worse as I drive. I've fixed the rubber hose (temporary fix, replacing all fuel lines this week). The stock lines are pressurized (ie no leaks after the pump). Could it be that the one stripped stud is what's allowing the fumes to escape? This isn't my first DSM, and I've seen cars run with two or three missing studs without leaking any fumes. Is there anything else other than the fuel send and return that's back there that I could check?
Also, any suggestions on what to do about the stripped stud? I've thought about tapping it to a thread size, any suggestions?
