What a rasslin' match! I removed the top, back and passenger side panels and exposed the generator. Nothing looked to be twisted, kinked or bass-akkerds so I decided to cut the fuel line and hand-feed the diesel to the pump. Held a squeeze bottle of fuel and squeezed the bottle while holding down the prime switch. Wahoo! She started and ran fine .... for about three minutes. After scratching my head and going through the process a couple more times, I wisely decided to check the error code. DOH! Now we know the cooling fan does little or no good with the cowling off. I assumed that was why I was getting a over-temp code anyway. Put everything back together and she cranked and ran for an hour with both AC units on full blast. Got my fingers crossed that the problem is solved. Still a little leery about the fuel pump sinse it apparently did not move enough fuel to fill the new filter. Don't know if there is some way to purge air other than the prime button or not, but as soon as I force-fed fuel to the pump, the engine started.
