Symtoms and cures for vapor lock
I have noticed lately that when my truck gets hot from highway driving or even in town driving, the truck will have a low idle and sound like its going to die. It also sometimes wont start if it has been sitting and I have to use starter fluid. When this happens, gas is still squirting from the accelerator pump though. Tonight on the freeway, when ever I came to a stop, I had to keep my foot on the gas and brake to keep the truck alive. I also noticed that the clear fuel filter was empty and only little burps of fuel was going through it (I couldnt believe the truck was still running). The fuel pump is new. Could this be vapor lock? What are ways to cure this?
