about 0 ohms full, about 70 ohms empty.

Let me give you a timesaving tip which may eliminate the need to pull the
sender..

Remove the tank cover under the carpet and find the 3 wire connector on
the sender. On mine, the 3 wires are marked [*W* yellow wire for the low
fuel light]  [*G* purple wire for float level sender]  [*t* Brown ground]
remove the connector and jump the float level G (purple) to the ground (T
Brown). Turn the key to energize the gauges and the gauge should show
full. If it doesn't (mine only goes to 7/8), the problem is not the
sender, it's either resistence in the wiring, connectors, guage flex PCB,
or the gauge itself.

If you are going to pull the sender, a large pair of channel locks and a
shop rag or rubber strip will loosen the cap. It is plastic, so you want
to be carefull not to deform it. When getting the cap back on, I had to
lube the threads because the cap wanted to bind and cross-thread on the
tank. Snug is fine, your'e compressing a rubber gasket and you don't want
to torgue the hell out of a plastic cap.

If you dissassemble the sender, you will see the float riding on two
wires. Clean the wires and float contacts. They are delicate, so be
careful. You will see the contact for the low fuel light at the bottom of
the assy, the float drops down and takes the switch to ground.
