carbureted or fuel injected? Keep them insulated from heat. Vapor lock means the fuel has boiled which is caused by heat and pressure drops.

It shouldn't be boiling unless the tank isn't vented and the lines are too close to a heat source.

thanks vile. i made a bracket for the fuel line to sit off the valve cover, which i think was the problem.
