Your biggest issue is that there are very few places that work on generators.
There is no industry standard on this type of work.

RV places if they do work on them are generally very high priced and likely to "sell you a bill of goods" is how I would put it.....

We get cutomers all the time that show us bills from RV facilities and they are usually very high.

Onan is owned by Cummins.....and some places that are listed as doing Onan repairs are primarily big truck engine repair facilities....

You are probably being charged a lot of diagnosis time. Maybe they spent half a day trying to decide what was wrong with it.

I work on them all the time and often let one run outside for hours waiting for it to fail so I can test it after it fails.

We don't charge hours and hours of labor for something like this.

I also do repairs based on my experience with these machines and fuel pump failure is high on the list.....
