Hi my name is Robert...
Not sure what you have tried, what I might do is loosen the fitting on the fuel filter and then prime the generator with the switch on the generator until you get flow and then tighten up the fitting on the filter and see if it will fire off. I would have a small can under the filter to catch on fuel. You would hold down the control switch to the stop position to get it to prime for at least 30 seconds... Please let me know if you need more help, follow ups are included... Robert
I agree that it is air bound, I did not know if cracking the filter line and priming would get fuel going. I would say loosen the injector lines and then try priming but I have never had to do that on that model. There is another tech. that comes around that specifically works on these generators, if you would like me to put your question back up for him please let me know... Robert
It should be priming, you should hear it as well when the switch is held down, the only other thing you might want to try is crack the injector lines and try priming again until you get flow. IF that does not work please let me know, there is an Onan tech that comes around he might be able to assist.
So it appears the issue is it will not prime from the switch when you hold it down to stop (outside switch) it should prime, you would hear some clicking when that is occurring. What I am going to do is put your question back up for other experts. I do not know when another expert will respond, they come and go daily, may not be anything you did wrong as it is required to prime the gen. with the switch after you change the fuel filter or replace a line...

Hello, my name is ***** ***** I am going to assist you with this.
If you replaced a rubber line, that is the fuel return - not the supply.
When you press the STOP/PRIME switch and hold it, is the light flashing in the switch? Remember, you have to hold the switch for at least 3 seconds before the fuel pump activates.
Sorry, but I had to work overtime tonight, and I just got home.
You have not been referred to 3 techs. The first expert realized that this was beyond what he can do, and opted out. I then took over.
I work 2 jobs, and help on Just Answer in the evenings. I can not be online 24/7.
Since the pump is not pumping when you press the PRIME switch, you need to go in and see if you accidentally unplugged the fuel pump when you changed that fuel line. Also check the ground wire and make sure it is not broken.
If it is not unplugged, unplug it and test the wire for 12V while pressing the prime button. If it does not have 12V, let me know.
If it does have 12V, try jumping 12V directly to the pump. If it does not run, the pump is bad.
