Fuel Gauge Sender
Disconnect wire and remove the fuel gauge sender from
the fuel tank.
Install an ohm meter between the terminal and base.
With arm completely down (empty position), resistance
should be 240–260 ohms.
With arm completely up (full position), resistance should
be 29–34 ohms.
NOTE: Bend float arm, if necessary, to get proper gauge
reading for a 1/2 full tank.
Make sure the sending unit is completely dry
(no fuel on it) before testing. Perform test
away from fuel tank to prevent an explosion or
fire from sparks.
