2. Check that the float moves smoothly between E and F.
3. 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	181.9 to 177.9 (7.161 to 7.003)	12.0 to 18.0 Ω
   	1/2	99.5 (3.917)	212.5 Ω
   	Warning	32.3 (1.271)	375.4 Ω
   	E	0 (0)	405.0 to 415.0 Ω

4. Reinstall the fuel sender gauge assembly.
