Fuel Gauge Inoperative after deleting one tank.

[SEAND]

I purchased a 1982 4x4 Silverado. The original owner deleted one of the duel tanks. He replaced the passenger side tank, pump and sender. He said the fuel gauge has not worked since. Any ideas would be greatly appreciated.

Check your switch on the dash, should be on the primary (passenger side), When you switch the tanks, the fuel sender also switches. Also check your wires at the valve.
