Recently installed 3 carb set up on 57 Olds 88. Vapor lock is now a problem. The following have been suggested: 1. Wrap gas lines in insulated material. 2. Relocate gas lines to different location. 3.. Install electric fuel pump. Being a novice (lousy) mechanic, I need HELP!! Would any of the above cure the vapor lock?? Anything to add or advise would be appreciated. Thanks, Bob auto@pa.net
