To get to the fuel pump, drop the generator (exhaust off, 3 AC wires, 1 12V DC, fuel hose, and 1 snap connector, 5 bolts). Remove the top of the green box (4 torx heads, lift off).

The pump resides in the left rear corner, taking the service access door as 'front'. About $60 at the Onan dealer. Be wary; somehow they sold me an identical pump, except the outlet was facing the opposite direction and the bracket was about 3/4" too low. Compare carefully before installing.

Have fun! I sure did (ha!)

Shortly after we bought our 2007 RT 210 Popular in March 2007 we experienced the same problem. Had it to the Dealer & the third time they discovered that the the Oil Sensor was not working properly. Haven't had a problem since they replaced it.

Thought I would give it a try this morning while it was still cool.
After 1:30 minutes running under load I came in to getting something to eat. When I went back out in about 20 minutes it was still running but started surging and then quit. Started it again and it ran for about 20 minutes then quit.
The spark arrester should be an easy one to check so I will do that first.

CJBill, your description with the fuel pump problem sounds like it could be the same problem. I will check the old service manual and see how much work is involved in getting to it.

Any more ideas keep them coming.
Thanks all for the help.


My memory is faded on doing the spark arrestor, but I remember that you need to mark the position of the screw, or it will be really hard getting it lined up, and the screw back in, when you reinstall it. Maybe Jim remembers better than me.
Oh, and if I remember correctly, changing fuel filter is no walk in the park either.

I fixed it. I guess you could see where my mind was at.

Yep, I'd sure try the spark arrestor first... and spray _lots_ of solvent over a few hours up into the area before trying to pull it out. BTW, the 2800 weighs 113 lbs. if you do have to pull it.

I have been following this thread and more about generator problems with the 2.8 Mine has been acting up for the last year. I changed the filter and yes it was a pain. No help, it still ran bad,with a load on it, it would really surge and then cut out. I was guessing that it was the fuel pump after it would run for 15 minutes then quit. Then this thread came up and I dropped the generator onto wood blocks and changed the pump. It is now running as I type and running smooth. Another thing that surprised me was all I had to disconnect was the fuel line, all other wires had plenty of slack so I did not disconnect anything else except the battery. The whole job took less than an hour. I want to say thank you all for the information.

Liketoroam, glad to hear that it's working for you. It's so much more satisfying when you do it yourself, instead of signing a credit card slip, ain't it? Congratulations on not having to do a full disconnect.

Mine has stood up to two three hour loaded runs so far, but we just haven't had the really hot 90+ weather here that my issues happened in earlier. So I'm just giving myself a conditional 'good to go'.... It's definitely quieter inside since I got it 1/2" away from the bathroom wall, added some more sound-deadening, and replaced the missing motor mount. Probably about the same outside, but I haven't checked it with the db meter yet.

If you haven't already done so,I would change the spark plug just for good measure.A friend did this with the same symptoms and it cured his trouble.
