Vapor lock
I have a 70 3/4 ton GMC. I am having a problem with Vapor lock. I have replaced the filter and fuel pump. I finally figured out that the fuel line from the tank to the pump is getting hot. The exhust pipe runs right between the starter and the frame. And it all gets very hot there. I figured out this was the problem by running it till it was hot and was starting to vapor lock then spraying water on the frame. It started pumping fuel great again after it was cooled.
I have I believe a stock 350 in it. No headers etc. I am considering rerouting the fuel line. But, I have never seen anyone else discuss this problem. Have you had the same problem? What did you do about it? If you have not had the problem am I missing something? It seems to me that if everyones truck is set up like mine they should all have the same problem.
