CHEVROLET TRUCK ENGINE PROBLEM

1981 Chevrolet Truck • 195,000 miles

Vapor lock on 454 engine? Truck starts up fine and runs good but once stop and sit for an hour or less is tough to start and keeping running.

Vapor lock generally happens while driving what maybe happening is heat is boiling gas in carb. What type carb is on and are using non OEM fuel pump ie. Performance like Holly or Edelbrock?
