Yes I do and I have the fuel pressure set to 7 psi. When the engine lays down the the fuel pressure will drop to about 1 psi or less. However this problem goes away when the weather is cool, about 65 degrees or less.

Since this type of setup has worked for me before (20 plus years ago) and since it seems to be so temperature sensitive I am wandering if the fuels blends available today may vapor lock much easier than before. Does anyone know about the fuels we get today? It seems it might blended different (vaporize much easier) since everything is fuel injected today.
