Has anyone had an issue with vapor lock in a TR3? A few weeks ago my car sputtered to a stop 3-4 times before it finally quit and would not start. On side of road it would run at idle and higher REVs, but would sputter again after I pulled back onto the highway. It had been parked in hot 95 degree sun for five hours at a Central PA car show and air temp was still in upper nineties on drive home. Had to be transported home on flatbed truck.
Car started the next day and has run without problem since then (have not driven in similar hot weather). Everything in electrical system is new and checks out. I did put can of dry gas in tank during problem (did not help), but had nothing to cool gas line by engine. Am still running on same tank of gas. I am wondering if the addition of ethanol (with a different vapor pressure) to our gas has caused similar problems in other cars with mechanical fuel pumps? I am installing an electronic fuel pump which should correct for a vapor lock and or a bad mechanical fuel pump. Any feedback would be appreciated.
