Anybody know what the ohm readings should be on the gas tank guage? Mine has been "bad" for over 20 years... and I'm finally going to do something about it... ha!

I'd like to do some measurements before I tear everything apart. Would like to know what readings I should get at the guage, and at the tank.

On my 38 the gauge reads from 5 to 35 ohms empty to full. The other side of the coin is that your dash gauge may be bad. If you use a variable resistor you can check the dash gauge first. Then if it is okay check the wiring to the tank. Then if all else passes the tests, drop the tank and check the float gauge.

The web page at <http://la.znet.com/~r1937/Fuel.htm> has a wiring diagram and details to repair fuel guage.
