[Silly Little Cars] Cushman police fuel pump

[Charles Lent]

Electric fuel pumps (if the right versions) are far better than mechanical fuel pumps. Yes, they supply fuel at pressure constantly to the carburetor when running because that's what they are designed to do,, but the float and needle valve in the carburetor should only be allowing the needed fuel to enter the carburetor. Old floats tend not to float at the correct level, and the tiny rubber tip on the needle valve do go bad. If the engine is flooding or gas is coming out of the vent on the carburetor, you should be replacing the carburetor float and needle valve and not the electric fuel pump. After adding an electric fuel pump to my 1987 Cushman, and rebuilding the carburetor including both a float and needle valve, plus a new accelerator pump and gaskets, my Cushman starts and runs far better than it ever did. Electric fuel pumps are designed to provide constant fuel pressure to the carburetor. It's the float and needle valve in the carburetor that regulate how much fuel the carburetor accepts. Save your money and rebuild the carburetor, but make certain that the rebuild includes a new float and needle valve.

Good day silly little car peeps,

Looking for a bit of help. Bought a 1994 cushman police with a Daihatsu 327 engine a few years ago as a project, but life threw a wrench into that plan.

Recently started working on it and realized the previous owner changed a few things and it seems to be missing a few things. The most obvious, he bypassed the original fuel pump and connected a 12V electric pump which spews gasoline into the carburetor none stop.

Does anyone here by any chance have one? Need to know a few things, if you don’t mind:
- Where do the four hose connections go?
- There is a screw-in connector missing on the side of my fuel pump that goes to the carburetor, what does it look like? Can you recommend an alternative?
- The manual says there should be a fuel pump rod, which seems to be missing on mine. Does it actually have one? What does it look like? Length/thickness? Material?
- Does it have an electric fuel pump?

Plan on swapping the engine for a VW type 3 down the road, but working with what I got for now. Any help would be GREATLY appreciated!

Javier
