Testing the Fuel Sender (continued)
Electrical System: Testing the Electrical Components
g191009
1. Sender full position
9. Use a multimeter to check the resistance of the fuel sender across the 2
sender terminals (Figure
A. The resistance with the float in the full position (completely up) should
be 5 to 8 ohms.
B. The resistance with the float in the empty position (completely down)
should be 89 to 95 ohms.
10. Replace the fuel sender if testing determines that it is damaged.
11. After testing, install the sender into the fuel tank and secure the sender with
the sender gasket and fuel sender cap. Ensure that the fuel fittings on the
sender are orientated at 90° from right side of the tank as shown in
184. Also, to prevent damage to the fuel sender during assembly, ensure
that the fuel sender does not turn as the sender cap is tightened. Torque the
fuel sender cap to 20 to 22 N∙m (175 to 200 in-lb).
12. Install the fuel supply and return hoses to the fittings on the sender and
secure the hoses with the hose clamps.
13. Connect the fuel sender connector to the wire harness.
14. Secure the sender cover to the fuel tank with the screws that were removed.
