Failing fuel pump

Also there are insulating spacers available (they profile the same shape as the gasket between the carb and manifold) that prevent the carb from heating up so much since it is sitting right on top of the Intake manifold. I had vapor lock at least a few times before i used this spacer that is about 3/4 inch thick. The spacer is placed between the bottom of the carb and the top of the manifold mounting location.

With these two upgrades, I have never again had an issue.

Once in a while on a hot day when pulling a big hill, I have had my 85 hp stutter (lack of fuel) but a quick toggle on with the electric fuel pump untill I crest the hill and all is fine once again.

Hope this helps you!

I've been looking for those insulating spacers but have not found one yet. I have a Holly 94 style carb. Can you point me to a vendor that has them?
