Onan Microquiet 4000 - Aftermarket Fuel Pumps

Hello all-

I believe my fuel pump is bad. My local source for Onan parts is backordered and Onan is backordered due to to C-19 and availability timeframe is unknown.

I see there are MANY aftermarket fuel pumps for this ubiquitous genny.

Have any of you used an aftermarket pump, and if so, what were the results....ex. how long has it been in use, fitment, ability to pump correctly, etc.

Thanks!

    eBay is your friend. Yes, lots of cheapo junk, but it works, maybe not as long, or youcan also find OEM parts there.
    I do not do Amazon because I do not hate our great country like Amazon does. Support American-loving companies.

    I'll start with the fuel pump and go there from there.

    I did an amazon carb for my Onan. It worked perfectly when we went out. I would bet your carb is shot.

    I bought one from O'Rielley's for under $20. Low psi is all the need to know.
