Fuel Sender

1. 1

   Turn the ignition switch OFF and disconnect the negative (-) battery terminal.

2. 2

   Remove the fuel pump assembly.

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

   Position	Resistance (Ω)	Capacity (L)
   E	298 - 305	2,7
   1/2	85,5 - 87,5	23,4
   F	14 - 16	44.1
