1957 Olds - Vapor lock-

[tentar]

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

With no offense meant:

 

Many conditions are called "vapor lock"; a few actually are vapor lock.

 

Perhaps if you described your symptoms, someone here might have suggestions.

Jon, My "vapor lock" starts in hot weather only - as hesitation for a few seconds followed by stalling.  Will not restart until cool down - 5 minutes or so.  Then will happen again.  Only happens in hot weather.  Thanks for your interest.  Bob

Have you considered phenolic spacers between the carbs and manifold?

Early Ford Mustangs were notorious for carb heating problems.

You could also try a fuel return line to the tank. You start by buying a fuel filter that has the return built into it. I have one on my 63 Pontiac, and it's a factory set up, however it was only used on air conditioned cars. This is doable. The fuel is always moving recycled, plus the fuel from the tank is cooler.

FYI. Always check your engine oil before driving off. Some of the fuel pump diaphragms will succumb to fuel that has ethanol in it. When this happens it will fill your oil pan full of fuel and wash out your bearings. Isn't government grand???
