21. Lower the vehicle.
22. Add fuel and install the filler cap.
23. Connect the negative battery cable.
24. With the engine OFF, turn the igni tion switch to the ON position for 2
seconds, then turn it to the OFF positi on for 10 seconds. Again turn it to
the ON position and check for fuel leaks.
SENDING UNIT REPLACEMENT 1. Remove the fuel tank.
2. Clean the area surrounding t he sender assembly to prevent
contamination of the fuel system.
3. Using tool J-24187 or equivalent, re move the sending unit retaining cam.
Remove the fuel sender and O-rings fr om the tank. Discard the O-rings.
4. If necessary, separate the fuel pum p from the sending unit assembly.
To install: 5. If removed, install the fuel pump to the sending unit. If the strainer was
removed, it must be re placed with a new one.
6. Inspect and clean the O-ring mating surfaces.
7. Install a new O-ring in the groove around the tank opening. If applicable,
install a new O-ring on t he fuel sender feed tube.
8. Install the fuel sender assembly as follows: a. The fuel pump strainer must be in a horizontal position, and when
installed, must not block the travel of the float arm. Gently fold the
