You aren't reading the entire code - the "3" is just an indication that there is a problem and a secondary code is available. Press stop and then observe the next set of blinks. The secondary code will be two additional digits (see your Onan manual for instructions). You can re-display the last code at any time - press Stop three times within 5 seconds and the previous stored code will be displayed.

Until you read the full code, you can't be sure that it is a fuel shutdown. If it is indeed a lack of fuel, the secondary code will be a "36".

Fuel gauges aren't all that accurate so I would not trust any of them until they have been calibrated.

My Generator and Aqua-Hot Webasto burner both shut down from lack of fuel when my fuel gauge is somewhere between one quarter and one half tank.

One day when they did shut down and I was leaving on a trip to Homer and Seward the next day, when I did fill the tank the next day it took about 85 gallons of fuel to fill my tank. The fuel tank is rated for 128 gallons, so if you do the math there was about 33% of fuel left in my fuel tank when the Generator and Aqua-Hot shut down.

Since leaning that important information I now make sure that if stopping for the night or for any length of time where I need both the generator and the Aqua-Hot I make sure that my tank is over one half full or higher.

It's all in information management.
