onan fuel pump

I bought an Airtex E11015 pump for our Onan 5500W generator 4 years ago. No issues with it so far. Got it on Amazon for $34 at the time. It's currently unavailable, but you can search other sources for this part number. It is a direct OEM replacement. Link to original source: https://www.amazon.com/gp/product/B0076D5OI2/

For those unsure if this is a DIY type of job, I uploaded a video of this project here: https://www.youtube.com/watch?v=nyHNPczC2YQ

Good luck.

The same fuel pumps are used on riding lawnmowers,paid $20 for the exact same part w/o $300 ONAN box.

Discount Auto sells Mr Gasket brand in different PSI.
I needed a lift pump for my farm tractor and they also sell one for diesel fuel, about $60. last time I looked.

I found a carter Universal fuel pump 4 PSI .....it says our original Onan pump PSI was six maximum so we're thinking this might work it's $57 from Summit racing I didn't order it yet but I'm thinking of it it doesn't work I guess I'll just resell it on eBay to somebody

They are all made in China. Just buy the cheapest one you can find. If the OEMs were made any better they wouldn't be failing at the rate that they do. I've never had to go back and replace a cheapie.
Cheap Fuel Pump Option

I replaced my fuel pump with an aftermarket from Amazon in October. The housing leaked fuel as soon as it started pumping. I was stranded since it was hot and we travel with dogs so I ordered an OEM from Onan overnight. Noticeably heavier and more expensive but it worked.

Got my aftermarket from Amazon. It’s a low pressure pulse style pump. As long as it doesn’t exceed 7 psi then it will work! It’s been almost 2 years and no issues.

Camco Onan fuel pump

Find out how many psi it is, then buy an aftermarket on Amazon. I did that with mine about 15 years ago. Worked just fine.

Just a thought - maybe I should hook up each one and see which one shoots out gas the farthest?? Thoughts anyone???

I think it's a good idea. Try it and let us know if there is a difference.
You'll be replacing the pump anyway so it shouldn't take long to do the test.

On Our pump it is low pressure, so that test might not be a good test.

…Tried Amazon?
