I hope this is the correct forum.
When I purchased my 2008 3500 it showed a full tank of fuel, when it got down to a 1/4 tank I refilled it but it only took 10 gal to fill up and the gauge is still on 1/4.
The DIC says 103 miles to empty.
So the question is, if the signal for the gauge is coming from the ECM or BCM then the sender must be bad if the DIC is agreeing with the incorrect fuel level yes?
