Re: '32 901 Sedan - Vapor Lock

I had success in stopping vapor lock in my 47 Custom by adding a small amount of Diesel. A five percent amount worked well with no odor or smoking from the Diesel.

The underwood temperature in that car was probably a primary cause. I would need to use a rag to lift the hood to prevent burning my hand. The engine coolant temperature was in the normal range and the engine never overheated. But the high under hood temperature was something I had not experienced in any other car.
