I have a 2012 F350 with a 6.7L diesel. My fuel sending unit is bad I think. It is measuring 11.1 ohms at the sender with a full tank. Does anyone know what the sender resistance should be with the tank empty and full? Thank you.
edit- The fuel gauge is reading empty.

No info, but hoping to get some info too. Haven't checked the resistance on the sending unit but think I'm having a problem with mine too. Gauge is starting to be even less accurate than before when it gets down to the 1/4 tank or so level. DTE will read ~75-100 miles left, gauge will show less than 1/4 tank and low fuel will light. When I fill up, it'll take only 20gal (27 gallon tank). Not off by a huge amount but seems to be getting worse. Probably time to start thinking about a new sending unit
