Podoy 149-2311 Fuel Pump Compatible with Onan Cummins Generator 4KW Microlite MicroQuiet 4000 4Kw RV A029F889 E11007 149-2311-02 149231101 149-2311-01 12V Fuel Gas Pump

Extremely cheap fix if your generator runs for 3-10 minutes and just shuts off. I tried the “too much oil” trick that’s all over the web and this pump is what fixed it. I think when the fuel pumps start to go they can’t provide fuel when up to temperature. I ran my on board Onan 4000 for 45 minutes under hard load and it was fine. The only thing that worries me is how the factory fuel pump states low pressure only. I have not gauged the pressure this puts out so time will tell. No leaks, works just like factory. Buy some new fuel clamps that tighten by screw and expect some time to change this. Disconnect the batteries and remove the ECU (two torx head screws on the frame of the generator and one clip for the wire harness underneath the ECU) and electrical lines running to the solenoid. Removing the air filter cover plate can buy a little room. The factory fuel filter will thread into the inlet. I used a bit of gas Teflon thread tape for this and no leaks. I will update this review if any issues come about, but so far great.

Worked.

It fit perfectly in my Cummins Onan 4000 Microquiet generator except the ground connector is too small to fit the bolt on the generator. I had to cut off their connector and splice on the one from the old fuel pump. It was not complicated to install, just difficult because of the generator design. Cummins left a lot of empty space at the back of the compartment but chose to put the fuel pump partially under the electronics module so everything has to come out to replace the fuel pump. Bad design by Cummins. Be sure to splice the connector on before installing the fuel pump. It is much easier to splice it that way.

Operates as it should and a direct replacement for original. Ground wire lug is smaller so used mounting screw to secure.

Well I was nervous about buying this fuel pump. My generator in my class c is a Oman 4ky. It would run about 10 minutes then shut down for under frequency. I had a feeling it was starving for fuel but pump tested fine. Bought this pump and it came and the box was soaked in fuel. I opened it and the pump was in a sealed plastic container and dry, so not sure where fuel came from. I installed new pump and ran generator for over and hour with ac on high. It fixed my problem.

These pumps are not engineered to operate like the OEM part that ONAN uses, I’ve had these pumps fail within a short time of operation”””

I used this for the Onan 4000 Microquiet generator in my RV. The one screw that holds the pump in the bottom bracket was VERY difficult to remove, but this is not the fault of the replacement pump. The new pump works great. I replaced the filter at the same time.

This pump has intermittent operating issues. I ended up pulling it and biting the bullet to by Cummins. This is now in my RV toolkit as an emergency (roadside) backup.
