Fuel pump/fuel gauge sensor

Attention! Before you begin, please read the caution in paragraph 1 this chapter.

Withdrawal

Note: This operation will require tool 23-038, a large socket wrench with protruding teeth that fit into the slots in the fuel pump/pointer sensor lock nut. You will also need an assistant.

1. Eliminate residual pressure in the fuel system (paragraph 2) and equalize the pressure in the fuel tank by removing the tank cap.

Warning: Be aware that fuel remains in system components when residual pressure is released and take precautions before disconnecting them.

2. Make sure the ignition is off.

3. Turn out bolts or bend forward (depending on performance) rear seat cushion (chapter 11). Remove the plug covering the fuel pump/pointer sensor from the floor of the vehicle. Wash off the dirt from the outside of the tank and wipe it dry. Use a vacuum cleaner to clean the area inside the passenger compartment closest to the tank so that when the tank is opened, dirt, water or dust does not get into it.

4. Disconnect the fuel pump/pointer sensor electrical connector (see fig. 8.4).



5. To disconnect the fuel injection and drain pipelines from the serviced unit, release the coupling on each pipeline by compressing its locking tabs located on the fitting and tightening the coupling. Wipe off fuel spills with a rag. If the coupling is difficult to remove, then use pliers and a wooden gasket to squeeze the pipe out of the fitting. This may require considerable effort. Be careful not to damage components (see fig. 8.5).




6. Release the fuel pump/pointer sensor retaining ring by turning it counterclockwise. Use Ford Regulated Tool 23-038. If you do not have one, then you can use a hammer and beard or tongs. This will help, at least when removing (see fig. 8.6).



7. Pull out the assembly so as not to bend the float arm. The float lever is mounted on a spring-loaded rod, which ensures that it is pressed against the bottom of the tank. Pay attention to the sealing ring. Once removed, the assembly must always be replaced (see fig. 8.7, a, b).

Installation

8. When installing, use a new O-ring and keep the strainer located above the base of the pump inlet clean.


9. Align the assembly with the hole in the tank and insert it so as not to bend the float. Make sure that the float lever slides along the rod until the upper base plate of the block can be aligned with the hole in the tank and pressed against the o-ring. This will require some effort. Do not damage components. The specified Ford device ensures that the ring is pressed when it is screwed in without distortion relative to the tank.

10. Press down on the knot as an assistant inserts and engages the retaining ring. When it fits into the tabs on the tank, turn the ring clockwise to tighten.

11. Perform other installation operations in the reverse order of removal. Follow the color coding to get the fuel lines in place.
