If you remove the sender wire and it still pegs yopu have a wire grounded somewhere.Probally in the sender wire to the back.When it removed the gauge should stay at E.Only GM goes dead full if it looses a ground.Thats on of the tests for a Mopar gauge.Ground the sender wire with key on and it should go full.Sounds like its grounding the wire somewhere.Rocky



, pull the wire off the back of the gauge and off at the tank and check it with an ohmmeter and see if it's grounded , it shouldn't be.
