Hi all i'm new. I have a '87 B250 318 with a mech fuelpump and i am haveing BIGTIME vapor lock probs. what is the fastest and cheapest way to fix.

 

Move the fuel lines away from any heat sources such as heater/radiator hoses, exhaust manifolds, the engine block, etc. If that fails to solve it, then a thick gasket under the carb to help insulate the carb from engine heat will do the trick.
