2018 Thor Quantum RC25 Gas Tank Gauge Wrong

Just got my used 2018 Thor Quantum. It has a 55 gallon gas tank. I have filled the tank twice with the fuel gauge reading 1/4 tank and only can put in 30 gallons? Gauge problem? Anyone else having this problem?

Terry

I recently bought my 2014 thor Chateau 28Z and the fuel gauge was always reading empty when full. Before I took delivery I insisted the dealer fix it. They had to take it to a ford dealership who found a ground wire off.
There are several modes of failure which usually lead to empty of full readings. There is a resistance provided by the fuel gauge sending unit and it should vary. You may need to get a ford dealer to look at it (or other chassis manufacturer..)

I thought maybe you were implying it was Chinese made.

It says "Wrong" now.
