Full time electric pump will not produce vapor lock. Do nothing to it, reproduce the same conditions to make it quit on you again. Immediately open the hood, pull a plug wire, hold it near a head bolt, and crank it over. Watch for the spark. Short orange spark or no spark is not good. You want a strong blue snapping spark. If this doesn't prove to be the problem, then think about fuel delivery again. Alan

It was 97 degrees here yesterday and I was dumb enough to take my 49 to a nearby car show where it sat on asphalt for 4 hours. The hood was so hot you couldn't touch it with a bare hand. Left for home about two in the afternoon, and after a mile it started to buck and quit on me. Coasted into a safe neighborhood, got a ride home, and returned in the cool of early evening. It started right up and drove home with no problem. I run and electric fuel pump full time, have the mauual capped off. Assumed it was a fuel delivery problem, but based on this forum, am now wondering if it was the coil. Comments please.
