4. 4
   Turn the ignition switch OFF and disconnect the (-) battery cable.
5. 5
   Remove the fuel pump assembly.
6. 6
   Using an ohmmeter, measure the resistance between terminals 1 and 3 of the sensor connector (A) at each float level.

   Also check that the resistance changes smoothly as the float moves from "E" to "F".

   Position	Resistance (Ω)	Capacity (L)
   E	197 ~ 203	3,7
   1/2	64,2 ~ 68,2	26,7
   Fuel Level Sender Gauge (F)	6 ~ 10	52,6

Removal

1. 1
   Relieve the residual fuel pressure from the fuel line. (Refer to Fuel System - "Relieving Fuel Pressure in the Fuel Line")
2. 2
   Remove the fuel pump service cover (A) after loosening the screws (B).

   

3. 3
   Disconnect the fuel pump connector (A).
4. 4
   Disconnect the quick connector of the fuel feed hose (B) and the quick connector of the vent hose (C).
5. 5
