Hey guys, thinking about changing to an electric fuel pump to help with some vapor lock issues. Any recommendations on a good electric fuel pump? Thanks! -William

I've had it on for two years - no problems. I mounted it on the vertical piece near the fuel outlet at the gas tank; using the mounting that the fuel pump came with. Note: I had some rubber scraps from a bike inner tube - I glued a strip on the inside of the mounting. Also, I'm using a "Holley" fuel regulator/gauge that I mounted near where the fuel line comes into the engine compartment I only hear a slight "hum", when it's very quiet outside, at start-up". I ran the fuel pump control wire from the fire wall through the drivers side cavity at the kick-plate, under the carpet under the door sill, and behind the rear seat drivers side up & over the rear wheel house - and through a grommet down to the pump. I wired in a relay that goes to the ignition switch and a fuel-pump oil pressure switch: fuel pump is energized at cranking from the starter solenoid. When engine is running - powered through an oil pressure sending switch. That way if engine dies, fuel pump shuts off. Also - I constructed an electrical filtering circuit (not an absolute necessity!). And mounted in the trunk in a plastic box. See attached circuit diagram. This circuit dampens pulses/noise (if any) from the fuel pump. Also, keeps the +12V line clean so nothing is heard in the stereo. (I work in electrical engineering - I couldn't resist) lol
Thank you! That is actually in my price range and looks like it will work for what I will need. This is probably a stupid question, but when mounting the fuel pump, does it have to be vertical or horizontal or does it even matter? Thanks guys I really appreciate it!
Good question. Because of the logistics. I mounted mine horizontally. In addition, even though there is a screen filter inside the gas tank (connected to the inlet pipe on the sending unit), I mounted an additional filter at the inlet to the fuel pump (just in case). I don't believe that it will make a different in mounting...? (Anyone else have comments?) I'm on vacation, right now. So, I don't have the instructions with me. Perhaps look "on-line". I recall that I bought mine on Amazon. Though MANY auto parts carry them. I believe that Summit and Jegs carry them, too.
Attached is a circuit diagram to add a fuel pump oil pressure sending unit. I used a brass "X" fitting to thread in the oil pressure gauge sending unit, "idiot light" sending unit, and the fuel pump oil pressure sending unit.
