    Bought a new sending unit from Classic Car Auto Parts. Gauge reads 1/2 full on empty , no gas in tank. Ohm meter reading is from 10 to 75 which is what Classic Car said it should be. Checked sender with two different gauges and both read same 1/2 full with no fuel in tank. Checked and have good ground. Anybody else have problems with these early C body fuel gauges?

    Usual issue is the tank sender isn't grounded well. I solder a tab on the senders to attach a wire to run to a good ground. The factory (at least on later cars) always put a clip from the sender to the fuel line to provide a ground, but that can get a little iffy.

    If it's not that, you can use a Meter Match to make it all read correctly. My adventures:

    Another issue is that some of these sending units are a more or less universal fit that can require some bending of the float arm. If you pull the unit and you can let the float arm drop to the bottom of its travel. If it reads empty at that point, the float arm will need to be bent to correct the error. Be sure to have a good ground when trying this test.
