Well, my sender jumps around from 35.5 to 90 at full when I wiggle the arm,
and reads  infinity at empty.  I'm getting a new sender.

Thanks for the help!

37.5 Ohms full, 290 Ohms empty.

For checking the fuel gauge, Bentley says set the special VW1301 tool to
55 for full, 560 for empty.

The VW1301 tester is a 10 ohm resistor, in line with a 500 ohm rheostat,
graduated 0-1000. So, ohms = 10 + 1/2 the setting. 55 -> 10 + (55/2)= 37.5,
560 -> 10 + (560/2) = 290.
