replacement fuel pump - carburettor bike

[buzzer]

has anyone replaced the fuel pump on a carb Monster with an electric one?

If so what pump did you use?

I haven't, but you'll want something low pressure. There's a bunch of not very elegant looking pumps on Amazon in the 2.5-4 psi range that would work.

Too bad you already painted your tank. An old carby SS in tank pump would fit the bill, and someone with your skills could figure out how to mount it in the tank.

Thanks,  I still have the option of mounting it in the tank as the hole for the original ST4 pump is 5" diameter.  However, I worried about sealing the wires where they pass through the plate, this is a common failure point, particularly on Multistradas.

I had hoped to get away without a pump and rely on gravity, but the shape of the tank, position of the carbs means there is but a trickle when the fuel is low in the tank.

Looks like I have managed to find a suitable pump, .  it feeds some big engine bikes so it should be OK..

FWIW, I repaired an old Husqvarna chainsaw fuel tank with JB Weld, and as far as I know it's still fine.

As long as the pressure is low, you'll be fine.

The wire pass-thru is a problem on 749, Multi, plastic-tank Monsters.
All later model bikes than ST4.
I've not seen a problem with the pass-thrus on *that era of bikes.
