I don't think an electric pump in line with a mechanical fuel pump is necessary. It's just more stuff to leak and fail. These trucks work fine with a plain old mechanical fuel pump on the engine. I have a plain one port in and one port out mechanical fuel pump and Quadrajet mounted with a thin gasket on the intake manifold, and run gasohol, and live in a very hot area of the country. It's fine. I have only a short piece of rubber hose connecting the steel line under the cab and steel line on the frame, and a short piece of rubber hose connecting the steel line on the frame and the fuel pump on the engine. All the rest of the fuel lines are steel. Quadrajet has a fuel filter inside. If I needed a fuel filter inline, I would put a metal-case one at the rubber hose connecting the steel line under the cab and steel line on the frame.
