Onan QG 4000 in a 2021 Momentum 25G

Does anyone know or where I can find the capacity of the fuel station tank? I put in 10 gallons and the gauge still reads empty.

According to the floor plan on the GD website is states 30 gallons.

Thanks, any idea on why the gauge wouldn't be working?

Thanks, how is it possible a main power line is not there?

Assembly line process is my guess. We have seen plenty of "why did they do that " questions 🤔.

Did you ever solve this problem?

My 2021 25G has a momentary switch you have to press to read the tank level outside.
Apologies for asking the obvious... does your unit have the press to read switch.
