Oais

Suggest you clean the orifice and change the stone filter behind the nozzle if you haven’t already.

No fuel could have a number of causes. Clogged nozzle, clogged filter, fuel solenoid malfunctioning, bad fuel pump, or air leak in inlet supply. The most obvious and most common is clogged nozzle. If you want to check the other potential causes then remove the fuel return line and run it into a jug. Turn the unit on and see if you are indeed moving fuel.

You seem reluctant to replace the nozzle. However that is almost always the first thing to do when a diesel burner is behaving as you described. Doug gave great advice. He always gives good advice

Plenty of fuel , got to try to get her going ,wife is wanting to go out west at end of may be our 1st trip

Just out of curiosity, do you have enough fuel in your main fuel tank. The Oasis is just like your generator, it will quit drawing fuel at a certain level.

Ah, the tech told me! You certainly cannot see through a Webasto/Agua Hot nozzle so that may be a very different animal. I can't imagine ANY diesel fuel nozzle that you could see through.

I can see through it. And tech told me it would be ok It isn’t getting fuel

I have never worked on an Oasis Diesel, but I have worked on scores Of Aqua Hot Diesels. The Fuel nozzle on an Aquahot CANNOT be cleaned adequately. You replace it. So, do you know if the Oasis fuel nozzle CAN be cleaned or do they require replacement? The fuel nozzle is what gets clogged and stops the flow of fuel. The Manual I found states to replace the fuel nozzle/nozzle filter/o ring for the regular service. Doug

Oasis makes an LP and a Diesel. If yours is Diesel, did you replace the Fuel nozzle? Doug
