With the many blends of oxygenated= =20 fuel on the market, if I was running auto gas I'd be darn sure it wouldn't e= at=20 my tanks. A fuel cell would assure you that this wouldn't happen. These cell= s=20 are alcohol safe, many of the cars run alcohol straight so the cells re= sist=20 both. Glad you are OK Jim,  be really sure of those tanks before=20 continuing,

&g= t;=20 Next project =E2=80=A6 perhaps an aluminum fuel tank.
