need some suggestions here last week i was running a little hotter than normal do to the weather i believe it was 90* w/85% humidity witch was no big deal never got over 225 ran fine tell the last few laps we have a bunch of restarts and when i got on it it just fell on it's face. it was like nothing was there but once i got it going it was fine untill the last restart we had then it wouldn't turn over 3000. when i got in the pits i noticed that my fuel line had been rubbing on my bottom hose. and after the nite was all done and it was cooled down it ran fine again like nothing was wrong. is it posible that the fuel could have gotten to hot and wasn't burning right or should i look some where else.

Yoy are a victem of vapor lock - the fuel is boiling in the line. Reroute your fuel line as far away as possible from any source of heat, try puttin an insulating sleeve around it.

On my gas line I use that pipe insulating foam kinda like roll bar padding but smaller and wrap it in black tape. Seems to work.
Did you ever think about making a cool can for it?

we can't have any cooling devises other than a radiator and a tranny cooler it's never happened before in three years so i think it was just a freak deal the way it was laying on the hose like hopefully that steal line will fix the problem
