I have a 1992 Tioga Montara with an Onan Emerald Plus 4000 generator. I was able to get the thing running after cleaning the bowl under the carb and getting all the gunk out of the mixture screw holes.

It runs when I place a hose in the gas can.

I replaced the metal fuel line hose all the way back to where a line comes from the tank.

I replaced the inline fuel filter. AND I have a full tank of gas.

I have not tried to drop the tank yet "because I have a full tank of gas

The generator will pull gas through 15' pr so of fuel line placed in a gas can. so that isn't the problem.

Is there a fuel shut off switch somewhere I do not know about. I checked around the camper and on the generator and haven't seen anything.

I am not sure what else to try before I have to siphon out all the fuel from my gas tank to drop the tank and look inside.

This is a gasoline Onan generator, not a LPG.

Thanks upfront for any assistance.

Try removing the gas cap on the tank and blowing compressed air in the generator fuel line backwards to the tank. My line was clogged in the tank and that fixed it.

Is the "15' of fuel line" you're using in the can the dame one that actully runs to the tank, or is is it new? Just wondering if you have a leaky line that's letting some air into the line between the fuel level in the tank and the pump. Maybe an old cracked line, or a loose fitting.

Have you checked to make sure the genset's fuel pump is working? It is on left side of genset down toward the mounting pan.

No some gas units have electrical shut offs. My Emerald plus 4000 does not.
The genset vacuum can suck fifteen feet, but will not provide sufficient fuel for much electrical load.

Yes the pump is working because it will suck gas through about a 15' piece of hose placed in a gas can. Thanks. Do you guys know if there is some type of fuel shut off valve or something or does that only pertain to LPG generators?

I have a Kolher 4 KW Gas unit and it does have a Fuel shut-off Soleniod. It was bad when I got it, I just by-passed it and it ran. Would not recomend running unit without it other than just to see if it will work.

I think I have the same generator that you have and I have never seen any automatic fuel shut off mechanism and don't recall seeing one in the repair manual either. I like the idea of removing the gas cap and blowing the line clear.
