Default Surge tank lift pump

For those using a surge tank, what kind of pump are you using for a lift pump to fill the tank? I’ve got an in-line Carter pump, but it’s high pressure EFI pump from an old project. Let me know what you guys use.

Depends where you're lifting from and the type of pump/flow you need.

If from an OEM tank...then any drop in pump will be fine

And the pump will only make high pressure if there is something to create pressure against. Otherwise it'll just move fuel regardless.

Stock pump external from BMW here. Since it's not doing much, I pwm it to run quieter and lower current.

Some older BMWs have split fuel tanks and have a very lightweight lift pump inside, but the one I use is a standard fuel injection version.

This is similar to the one I have. It can handle stock EFI fuel pressure, but it's coasting as a lifter pump.
