100ll fuel line

NO, I've ran it solely in my car for years. Actually in my lawn mower and other things as well and it's the best gas I've ever used. I've turned away from it this year just because it's not as convenient. But I sure do miss it and it's not doing anything to your fuel lines it's just bad luck and you got a leak. Anyways if it would have been that non-ethanol crap it would have been a plug LOL
