Jeff, when I had vapor lock issues on Argentine Pass with my 40, Justin from Redline suggested installing an electric in-line fuel pump before the manual pump. He said the manual pump would then act as a regulator, keeping the fuel line pressure to spec, but the electric pump would eliminate the vaporizing issue. My question is this...why do you suggest an in-tank one instead of this seemingly less complicated alternative?
