Gasoline Odor

Frank,
I am so glad you have written a letter to Cummins Onan.
Now there is a paper trail if something fails.

My generator started to put off a gasoline vapor odor inside the coach after shutting down. I was just running my monthly maintenance cycles with a load in the campground. This happened twice on hourly runs so I decide to stop using it.

Can you imagine a gasoline vapor leak mixing with your propane hot water heater ignition?

2013 3051 Generator Fuel Pump Leaking

I decided to start a new thread because I believe all owners need to be aware of a potential problem with the generator fuel pump leaking fuel and causes fuel fumes inside the coach while running the generator.

Trwmodela and several others brought this potential hazard to my attention. I called Cummins Onan earlier this week and the service advisor informed me there was no campaign on replacing the fuel pump but there was a fail/replace service bulletin if the part fails to replace it as needed.

I contacted Cummins Onan Corporate today to get approval today to have my generator fuel pump replaced because I believe it to be a safety issue and do not want fuel fumes ever to enter my coach while operating my generator.

For those of you who are in my situation I urge you to contact Cummins Onan to have your defective fuel pump replaced with a new/improved design that will correct this problem. Below is the response I received via email:


Dear Mr. Reckenberg,

I understand your concern about fuel pump reliability. The safety of our products is very important to us. I am currently unaware of an issue with KY fuel pumps leaking fuel or fumes. However, if you feel your fuel pump is not operating correctly, please contact your nearest distributor, as your generator set is still under warranty.
For more information, manuals, parts and service as well as sales and pricing inquiries you will need to contact your local Cummins Distributor. You can find your local Cummins Distributor at www.cumminspower.com (for commercial products) or www.cumminsonan.com (for consumer and RV products) or in North America call 800-888-6626 and select option 1 to connect you with your nearest Distributor.

Regards,

Chris

The Cummins Onan service advisor will not replace the defective fuel pump until it fails. I understand that when this pump leaks fuel the fumes can enter the coach and create a potential safety hazard.

I will continue this crusade until all RV owners with the defective fuel pump get them replaced free of charge by Cummins Onan. The service bulletin must be upgraded to a replacement campaign before someone becomes ill from the fumes or lord forbid, get hurt. I would like to see Forest River use their leverage to help us too. I can not believe they are unaware of this potential safety hazard since their is a service bulletin already in service.

Frank

Are there any identifiers to determine which units are affected.

Cummins Onan would not give me that information but I had to give them the serial number of my generator. I wasn't given access to the service bulletin information from the service advisor.

Does anybody know how far back the problem goes? My Sunseeker was made in May of '12. Could it have the bad parts? Thought they were mostly newer generators. But sometimes it's difficult to start which makes me wonder. I took it to a Cummins Onan location to have the unit serviced (oil change) about 3 months ago and they didn't say anything.

From my research mostly on Forest River forums. It was 2013 & 2014 models that are having the fuel pump problems.

I'm not convinced this issue will ever be resolved. I have a 2014 Sunseeker with the Onan. Onan has replaced three pumps on mine, twice in Orlando and once in Amarillo. Each time it was stated it was a new version if the bad pump. Well, now it's starting to fume again, so it won't be long until this one fails. I assume right after the warranty expires. It's an inconvenience, but I feel a major safety issue as well.

4GCampers,
I would also suggest you write a letter to Cummins Onan Corporation. Provide copies of your repair orders and explain the ongoing concerns.

As you can see from the email correspondence, the Cummins Onan staff is not familiar with the issue so that is the 1st step. I spent a lot of time studying the manuals that came with the generator. In my opinion, Onan increased the fuel pressure to help with the starting issues without redesigning the fuel system components to handle the increase thus causing seals and gaskets to leak.

Cummins Onan is a solid company and will stand behind their products; I believe. Their decision to find (then repair) is the wrong approach to the seriousness of this issue. Leaking gasoline coupled with fumes is a safety hazard in/ around our new homes. unacceptable, unacceptable and unacceptable!

Please write your letters and send them emails. Above all, keep copies of all your correspondences.

Frank

It would seem to me that you are very unlucky to get 3 bad pumps or the cause is with some other component in the system.

Onan makes generators for lots of RVs and it would be interesting if the problem is unique to FR products. Not sure since I have a 2012 with a Genrac, but I believe 2013 was when Onan became standard on the Sunseeker/Forester. Possibly they are specific models only used in FR Motorhomes. That may explain some of the Onan rep responses that they were unfamiliar with the issue.

I know based upon conversations with a Big Foot engineer that the leveling jacks used on Sunseekers/Foresters are custom made to FR specifications. If you independently have Big Foot jacks installed you will get ones with a slightly different design.
