JB Weld and Fuel
Does anyone know if JB Weld is resistant to fuel and if it could be used on a fuel rail to fix a leak. Wondering if fuel would destroy the integrity or if it would hold up to use. Any ideas or have tried it?

If a seam is leaking, it can be brazed closed, or even silver-soldered closed. Brazed with brass or 50% silver solder, the break will be closed up and a very strong repair. (When I convert a rail from quick disconnects to AN fittings, I silver solder them on and pressure test them to 100psi with compressed air, no leaks, no worries

I also wouldn't use JB weld to patch a high pressure leak.
not sure if the cause was ever found. I know there was some speculation. I was just pointing out what could happen if fuel started spraying on jshelton'* headers if the job is not done properly.
Mike'* car was found to be flooded at one time. The resulting electrical demons eventually took his car out.

JB weld won't hold against that much pressure when applied from the outside only. Been there, almost burned that. Replace the rail, it'* much safer anyway.
