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

4. Reinstall the fuel sender gauge assembly.

3. Reinstall the fuel suction plate sub-assembly.

NG → See step   9 

OK: Go to next step 

1. Disconnect the D100 combination meter assembly connector.
2. Disconnect the J71 fuel suction with pump and gauge tube assembly connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   D100-16 (L) - J71-2 (FS)	Always	Below 1 Ω
   D100-16 (L) - Body ground	Always	10 kΩ or higher
   J71-3 (FE) - Body ground	Always	Below 1 Ω

4. Reconnect the fuel suction with pump and gauge tube assembly connector.
5. Reconnect the combination meter assembly connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
