The manifold vacuum seems to be consistent, so I don't think it is a vacuum leak. This leads me to the possibility of the fuel pump causing issues when it gets hot. Considering the crap oxygenated fuel we have here in Southern AZ, I am considering going to an electric fuel pump to eliminate possible vapor lock issues. My question is, do I have to run a return line to the fuel tank or can I just install the pump and be good to go.
