Re: ‘56 400 vapor lock

I have a 1955 Clipper Custom, I live in Phoenix, Az. I experience vapor lock when the temperature is over 95F. There has been a lot of talk here on this website about vapor lock. Today's gas is to blame. All I know is that I use a mechanical fuel pump until I experience vapor lock and then I turn on my electric fuel pump. I am on my 2nd electric fuel pump. I have been driving my car for over 20 years and have put over 70,000 miles on it. I don't know everything, but I have experienced vapor lock. At over 110F, I will drive my Clipper, my wife will not be in the car, and the electric fuel pump is on. Good luck and get an electric fuel pump, put it by the gas tank. But continue to use the mechanical fuel pump.
I also use a Chrysler mechanical fuel pump, it isn't affected by today's fuel. Look in the Parts Cross-Reference and find it there.
