After several tests I have done to troubleshoot the problem, I have determined that it is not getting fuel. When I use starting fluid it will fire, but will not continue to run. The fuel line from the main tank appears okay. No fuel comes out of the hose that goes into the carb when cranking.
I have narrowed it down to a clogged filter, or a bad pump. Is there a possibility of another issue like a safety fuel shutoff? I want to fix this myself. I think I can get at the fuel pump and filter without pulling the generator out of the coach. Is there a test I can do to verify that the pump is good or bad? Thanks for your help!

Look also for hidden in-line filters somewhere between the tank and the generator. To be safe, replace all existing fuel filters. If the unit does not start using the portable fuel supply, remove the fuel solenoid temporarily and connect the fuel line directly to the carburetor. It is possible for the solenoid to become faulty, fouled or plugged. If the generator starts, replace that solenoid. In some extreme conditions, it may be necessary to measure the actual fuel pressure at the carburetor. A weak fuel pump may be at fault. I’d recommend a professional RV shop if it comes to this. If you have access to another fuel pump, you can swap it out also to be sure. But I’m betting on cracked a cracked fuel hose between the fuel tank and the generator or a plugged filter.
