The original rubber diaphragm and rubber o-rings in your 1986 aluminum fuel head are not ethanol tolerant.

Jim would you suggest adding some 2-stroke oil in with your gas?or maybe marvel mystery oil?If not what what would you suggest.Thanks Kevin

His diaphragm developed a hole in it, which caused an injector to never stop flowing. Nothing going to fix that but a new diaphragm. Would an additive help slow down the ethanol damage if used for years prior to his issue? No idea, but I would think something like Seafoam would be better than oil, no?

Thought so, just wasn't sure if you knew the actual problem he found when he pulled his apart.

Car runs great! But its December and cold here in NJ, so I may not get it back out for a while.

That was a fun video though! Glad you liked it!

No, I wouldn't suggest putting oil in the gas.
