This may not be a safe fuel fix for everyone to try, ...... that is, in everyone's case.

Could be incorrect, but it appears that if gas leaks here at the shut off, it could travel & trickle down between the floor boards, to a hot, rusty muffler below, when the engine is running, or ........ with engine not running, car parked, & the muffler is still hot.
