Question by  J (113)

Should you put a 6 volt electric fuel pump on an older car?

It helps them start, correct?

Adding an electric pump to an older carburated engine can improve starting in cases where an old mechanical pump isn't working. However it also requires adding a fuel pressure regulator.

you only use 6 volt parts on vehicles with a six volt system. a fuel pump does not help the car start it help pump fuel to the injectors or carb. if you put that pump on a 12 volt system you can damage the system and pump.

First check to see if the electrical system is 6 or 12 volt. No use starting a fire. Also, it might help to service the ignition system and carburetor.

I don't think there are any 6v automotive fuel pumps out there. Normal cars run 12 volts. Secondly if you install an aftermarket pump you will need a pressure regulator.
