Gas leak in petcock on CA77

[catterar]

Can JB Weld be used to seal a gasoline leak around the pressed in discharge fitting in the petcock? Or should I try to sweat it in?
Mine is extremely loose. I have tried tapping it in with a small hammer. It holds until I start the engine then it vibrates loose and begins leaking again almost immediately.

It's been my experience using jb weld on anything that touches gasoline will fail. Maybe others have had better luck. I would use gas tank sealer epoxy. The kind that comes in two parts that you mix together. It's made to stop leaks in gas tanks. It comes in direct contact and won't dissolve.

Thanks Mike,
I'll pick some of that up.

YES you can use JB WELD.

Thanks Loud Mouse,
One way or another I'll get that tube to stay put.
