Fuel Filter on Onan Generator
We have a 2014 Bay Star class A. I've had a few issues with the generator shutting off while traveling down the road. I doesn't happen all the time. It throws an error code 36 - Code 36 is Engine Stopped Without Command from Controller. A few people on the board have suggested checking the oil, changing the oil, changing the air filter, and changing the fuel filter.
The oil was in the middle of the safe zone. It was "supposedly" changed by North Trail last August when we bought our new coach. I am planning on changing The air filter, and the oil over the weekend. I cannot find the fuel filter.
Does anybody know where the fuel filter is on an Onan 5500 Gas Generator. I looked around with the cover off and can't see it? 
The Generator is an Cummins Onan 5500 5.5HGJAB K
Help!

The pdf referenced above shows two fuel filters - one on the fuel pump inlet and one on the carburetor. Sometime after 2006 or so for the JAB 5.5 Onan stopped using the one on the carb and replaced it with a fitting.
The one on the fuel pump can be unscrewed from the fuel pump from the outside unless they have changed that since 2006 or so. Just follow the fuel line from the tank to the gen housing (bottom left rear corner)- the filter should be screwed onto the fuel pump.

I assume you have plenty of fuel in the MH, gen is designed to shut off when you reach 1/4 tank on most MH so you don't get stranded.

Our generator does the same thing. Same error code. I found that the oil level must be at the full line most of the time. If it drops down to middle safe it will shut down.

Check my prior post on this issue.
The problem was do to the pump over heating.

I hope that it's something simple, because otherwise they may have my coach for a while, and that is not a pleasant thought. Thank you for the heads up about the fuel pump. If the simple stuff doesn't work, I will push them in that direction.

CharlieJ - The tank was just coming off full. I had probably 35 miles on the full tank, the first time it happened.
