Well, I am about 99.99% certain that Vapor Lock is the problem here. I live in Arvada (for those of you form CO) and I commute to the tech center everyday. Mornings are great, nice and cool, evenings around 4-5pm suck because of the heat and traffic. I can usually get to about Highway 36 before I have any problems, sometime farther. However, after a while my truck starts to shudder like I'm running out of gas, eventually it just stalls all together. This usually is noticible when I have to give it gas for a hill or something. It's happened twice now and only a rest of 3-4 hours will cure it. My question is, what are the solutions for vapor lock? I heard about the cloths pin deal but that did *not* work, unless I have them in the wrong spot. I have an 1986 K5 Silverado, 305 V8. If anyone could tell me where I'm supposed to put them that'd be great. Right now I have them on the metal (silver) line that looks to be about 6-8 inches long and runs from below a pump and the air filter intake. This didn;t seam to help at all last ngiht on my way home. I have about 5 or 6 pins on there. What else can be done? Relocating the line I hear about also, but is that easily done? It doesn't seam to be since I can barely tell where the ends of the line are, muchless be able to access them easily to move them. Any assistance you can provide would be greatly appreciated!!!
