Onan 2500 KVD problems
New to me 2009 Lance 845 with an Onan RV QG 2500LP generator with 40 hours total run time starts very hard and runs rough. It also appears to have an engine oil leak. When we looked at this unit the o...

OK I got the manometer tee'd in to do some more checks.
Static pressure with tank valve on and engine off it is close to 16"WC. Seems hi to me, but this is a regulator I am using just for testing. I will check pressure of the camper system when I re-install the generator.
Engine running with tank valve all the way open it is down to 8"WC, which seems low but that may be due to how rich the engine is running so it is drawing a lot more fuel then normal.
When I start shutting down the tank valve it starts to really smooth out close to 0"WC and it actually runs the best a negative 1/2" WC. Am I correct in thinking it must be the demand regulator? I am not sure how this system works, as I have never messed with LP fuel systems, but everyone in the trade refers to what I would normally call the carb as the "mixer", so I take that to mean it does not meter the fuel at all, it just mixes it. That leaves the demand regulator to determine fuel mixture or "demand"
I would really like to find a supplier for this part besides Onan as typically there parts are overpriced in my opinion.
Thanks!
