Hi there, Ive started having an issue with my 1967 elco, 283 engine. After about a 45 minute drive I will stop for snacks or what not and shut my truck off. When I come back a few minutes later to turn it back on it won't start back up. It turns over fine but just will not fire. After about 20 minutes or so it will finally fire but barely, I have to really push down on the gas pedal to get it to fire. Not sure what has happened or what is going on. I didn't have this issue last year. I've been told to buy some high temp pipe insulation for the gas line from the fuel pump to the carb as the temp of the engine may be boiling the fuel?? Have any of you had this problem with your Elco's ??
