Wiring at the fuel tank / extra grounding wire?

Not if it was the return line.
And then there's ruptured tanks...
Or, you are knocked out, but the engine isn't...
-Just sayin'

I don't think the inertia switch will help much stopping fuel coming out of a ruptured tank. Lol.

Agreed, but it might stop the engine before 13.5 gallons of gasoline are ignited by an exhaust leak (like the one you are currently working on) and burn your arse up.

Car runs well w/o the extra grounding wire.
