Oais

My oais is not getting any fuel , it started spitting and finally quit I put new o ring in and anyone have any thoughts

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

It is a diesel , a I cleaned nozzle

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

Is this in a boat, a plain or a spaceship? Sorry, but you kind of asked a question without any info. Your Oais or Oasis Hydronic heating unit has it's own fuel filter. When was the last time you replaced the filter and serviced the unit?

It may have quit for many reasons. My first suggestion would be to service the unit. You can buy the kit on Amazon. There is a YouTube video that will walk you through the service. It takes about twenty minutes and requires minimal tools. It includes the new fuel filter, air filter and igniter, which is often the problem.

If that doesn't solve your issue, give ITR, the parent company for Oasis a call, they'll walk you through diagnosis.
