Onan Generator Fuel Pump Replacement OEM: 149-2331-03 | 578907 by FlipMfg

Fixed my intermittent generator issues on my Onan 5500. Would run for about 15-30 with no problems, then randomly shut off. This fixed my exact problem after cleaning out my carb, changing all sorts of filters and plugs, etc. Fairly easy to install and I just used my old hose connectors from my old fuel pump. It's been working great!

Worked great. exactly what I needed

Installed this fuel pump on my 2003 Winnebago Rialta Onan generator. My generator would run for about 20-30 minutes then quit. When it ran it did not run smoothly, but had a surging type rhythm. After about 20 minutes I could restart it. Read on the internet where other Rialta owners had the same problem and installing a new fuel pump took care of their problem. I installed this fuel pump (which was easy to do) and now the generator runs smooth and no stalling. Excellent price. A local parts store wanted $150.00 plus labor for a replacement fuel pump and I could not find a cheaper price on the internet. Happy with my purchase.

Replaced my old fuel pump during regular maintenance, due to age, it worked fine. The new pump, great price, failed 15 hrs into use and I drove the last 150 miles from Fresno to my home with no air conditioning in my motor home cabin, 100deg plus outside. Will not purchase or recommend this supplier to anyone.

Perfect fit and function.

mounting bracket was not in the position shown on the picture. I had to build a foot to remount it on the additional foot and then drill the foot to mount into the original bracket. pump works fine but way more hassle than I wanted.

Not exact fit had to build bracket to make it fit

Fit perfectly! Would buy again if needed!
