  1. Check that the float moves smoothly between F and E.

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:

    Tester Connection
    		Float Level
    		Float Position (mm (in.))
    		Specified Condition
    1 - 2
    		F
    		142 to 152 (5.591 to 5.984)
    		13.5 to 16.5 Ω
    1/2
    		71.1 to 76.1 (2.799 to 2.996)
    		208.3 Ω
    Warning
    		5.9 to 10.9 (0.232 to 0.429)
    		365.2 Ω
    E
    		0 (0)
    		405.5 to 414.5 Ω

  1. Reinstall the fuel sender gauge assembly.
