How to test a fuel tank sender

[spadaforaj]

No matter how many times I try re-wiring my fuel guage - it is either pegged on full or empty and never moves - wondering if there is something wrong with the sender - is there a simple way to test it ?

Yes there is.

A simple ohm meter is all you need. The resistance in the output changes with the level of the float. It should have a steady change as the float sweeps through its travel. If it jumps around or doesn't move it's finished.
