Hi everyone!!

I was given a gift of a 34 foot Cass A motor home. It's a 1990 Fleetwood Bounder 34s and it only has 6800 miles on it. I'm brand new to RVs and I'm working hard on building my motor home knowledge. I need a little help with my generator. Its an Onan BGE, NHE Emerald III Plus gas generator. The thing has been sitting for at least 10 years unused. I just don't think that its pumping enough fuel. I changed the spark plugs first but when that didn't fix the problem I removed the fuel pump and filter and tried to just prime it to see if it would kick and it did. I'm sure its just the fuel pump. The fuel pump replacement number reads Oran part number149-2150. However I can't find it anywhere. Part # 149-2140 seems close. Did they change the number? Does anyone know if this will work? Is there a cheap genetic one that will work just as well? ($120 seems kinda high)

I have to order it on-line. Any advice is strongly appreciated.

I got mine on ebay for 35 bucks...........just make sure you get a LOW PRESSURE pump ,( 3 to 7 lbs ) and you will be fine.

GOOD LUCK

First, congratulations on your new coach.

Have you put a post under the Fleetwood Owners (motorhome specific forum) on here? They have a lot of information and postings on the Bounders on there. That is where most post their problems for help from what I can see so it wouldn't hurt to post your generator issue there.

You do know that you need at least a 1/4 tank of gas in order to have gas available for the generator, correct?

As for a pump, any low psi, 12v Facet pump will do...

Tyler6357 · 08-04-2011, 11:41 AM

Yes, I am aware that the gas tank must be at least 1/4 full, it is in fact 1/2 full but it's kinda old gas. Can you tell me how much the PSI should be (min and max) for the fuel pump? It's a 2cyl generator.

Alan_Hepburn · 08-04-2011, 04:28 PM

You will want to check, and probably replace, the fuel line from the tank to the generator. If it's been sitting that long the line most likely has some leaks in it and the generator is getting mostly air instead of fuel. You'll need to drop the tank to get at the line, but that might be cheaper than a new fuel pump...

Check the files tab of this site, I uploaded the Onan Generator service manual

The new Onan part # is A029F887. It is 1.5 psi. $105.00 and can be ordered directly from Cummins Onan online, most cummins dealerships, or any Onan service center.

Billieg · 08-04-2011, 07:01 PM

Also get your regulator # and get one on Ebay for around $45 instead of breaking down on the road and having Cummins charge you $490 for one.....

If it has sat for ten years then any gas that was left in the carb when it was last used has turned to varnish. I would recomend firdt pulling the float bowl off and cleaning it and the main jet. Most likely you won't be able to get the main jet clean and will have to replace it. Most likely that will solve your fuel problems and cost a lot less than a new fuel pump.
