Re: Pros and Cons of fuel return line...

Vapor lock occurs in the suction line from the tank to the pump. If it were mine, I'd use the recirc line style fuel pump. I have a small booster electric fuel pump to pressurize the fuel pump suction line to reduce vapor lock, since my truck does not have a recirc line.
