I can’t stop my 85 F150 from Vapor Locking?
Ok, here’s the problem. I have an 85 F150… It has a V8 2 barrel carb, 5.8L engine. When it gets hot outside, (and even at night when driven enough) it vapor locks. I have had a new head gasket installed, a new radiator, new water pump, new gas cap, and new fuel line. (The old one was metal, I cut it, put a new rubber fuel line on, and even insulated and re-routed the fuel line.) I also installed a new thermostat, (160 degrees), and even tried running it with the thermostat out. Still vapor locks. Also the thing over heats…. I”m not sure what the problem could be… I know I have two problems, a vapor lock, and an over heating issue, but me and my mechanic are at our wits end… If anyone can shed some light on this situation, I’d really appreciate it… Thanks for everybody’s time….
Bill, I think the timing may be off a little… I will have my friend check that as well…Also, I thought vapor locking is caused by the fuel boiling in the lines… All the fuel lines are insulated by thick foam, and also in a rubber line. My mechanic seems to think that I need a new plate on the bottom of the carb… Or something like that he was mentioning…
