ONAN - LP Liquid Genset not starting
I've searched through RV.NET, but haven't had success looking for information about my generator problem. I have a ~2004 ONAN 5.5HGJAB1271A Liquid Propane generator that won't start. My suspicio...

Thanks, all for the posts.
I've checked a few things, and have the following to report.
* LPG Fuel tank is 3/4th full.
* I checked for the valve at the tank and it seems OK.
* As far as I know, there are no other cut-off valves. If there are, they're in the open position because I was the last one to run the generator and I haven't shut anything off.
* Opened and removed the air filter cover and cranked through a few cycles (should cover the "intake" being clogged.
* I did find that the "oil drain" tube mentioned by Jim had completed disintegrated. This drain is now open, and draining into the engine compartment. Since it's not run much, there's not too much oil and none that's fresh. I'll have to replace the tube. My guess is the last mechanic replaced it with something not to code.
Now one more question:
* I'm new to decoding the Onan and thought that the LED under the LOCAL Engine switch would blink out codes if there was an issue. Since it's not starting at all is this an issue? I assumed it would report based on failure to start also. When i press the rocker switch "down", the light goes on, but stays on. No blinking.
If I decide to replace the "LPG Oil Drain Hose" myself, where can I find parts? I got the following from the parts manual, but I can't seem to find anything other than air filters, disposables and manuals on the Cummins ONAN Store: https://www.cumminsonanstore.com/store/search.asp
11 503?1952?06 2 Clamp, Hose - needs replacing
12 503?2171?01 1 Hose, Drain - needs replacing
13 504?0203 1 Valve, Fuel Shutoff - presumably OK
Thanks again for your help and your patience.
