    The rubber grommets for the bottom of the fuel pump housing can be ordered from Memphis. I went ahead and ordered 2 when i rebuilt mine. Little did I know each box contained 2 so I ended up with 4 total grommets. Send me your address and I'll mail you one if you need it Bergie.

    I rebuilt the pump and a few years later it went out again. I blame it on alcohol and water condensation in a part of the country with high humidity. Both pumps below have proven reliable in the configurations described.

    My replacement for the red truck is:

    Carter P4603HD Universal Rotary Vane Electric Fuel Pump 43 GPH 6 PSI Marine 24V
    This pump is not meant to suck. It is meant to be below the fluid level. I installed a 20 gallon fuel cell in the bed of the truck. I drive it in the yard. It takes me a year to burn 20 gallons. The problem of old fuel is eliminated with the smaller tank. The pump is below the box and is gravity fed. It has proven very reliable, but a very noisy rotary pump.

    The pump I used on the yellow truck is:
    24V FACET SOLID STATE FUEL PUMP 6-8PSI CARBURETED ENGINES ONAN 149-2035
    I use a small boat tank on the factory tank brackets. I assume it would work with the factory tank if you plug the bleed holes in the factory pickup tube. I added a regulator between the regulator and carb. The regulator is set at 6psi. It is reliable and my suggested replacement. This pump will suck for long
    periods without locking up. It will suck fuel.

    My fuel pump education is documented in my truck threads. I learned that most pumps will not lift (suck) fuel for extended periods of time. Most must be gravity fed and below the liquid level to be reliable. If you pick up a new Mr. Gasket fuel pump and read the package it now states it must be gravity fed. They worked great for about an hour and then wouldn't pump until shut down for a period of time. They changed the packaging after my 4th free pump replacement and a few discussions with the engineers.

    Ok, who sells the kit now?
    I pulled my pump apart, and it had one bad brush.
    Everything else seems it pretty good working order on the pump. The screens could be nicer, but they still work.

    I haven't see the kits in quite a while now. I have seen from time to time the complete pump for sale on the popular bidding website. They aren't cheap but are the whole pump. I tired to get a run of the rubber isolators made but the company never would do it. They had better things to do .

    Man, I only really NEED the brushes, those would seem like we could get them if we had specific part numbers for them.

    In my town there is a motor repair place. It's an old place and they work on all motors. They sell new ones as well. I bet if you took the brushes and the armature down to a place like that they could match it to an existing one.

    The one brush was toast, nothing really left of it to see what I even need.
    I can take it to a local old timer, he mainly does alternators, etc. Never know!

    I got a NOS one I’m not going to use. The only problem with it is the threads for the electrical connection are bad and need chased. Shoot me PM if interested. 1E388D6E-7B3A-4154-A499-FC2D35846583.jpg
