Re: Vapor Lock on a 370 Ford by Phil Feinstein
Post New Message 1 of 2 things typically causes a vapor lock: a kinked or collapsing fuel line/fuel vent line or fuel line running too hot or too close to a source of heat.

Here's what I would suggest. Inspect the fuel lines and the vapor return lines. pull the charcoal canister off the firewall or frame and give it a shake. If the canister rattles, that's one of many possible sources of your vapor lock problem. The electric pump helps a lot to prevent vapor lock, but the vent lines are critical. they need to be clear and free and one of the places they can fail is where the line goes from rubber to steel. Moisture collects and causes rust scale which can block the flow of fuel vapor.

Hope that helps!
