J 34730 Fuel Pressure Gauge

Caution: Provide proper ventilation when working with fuel in enclosed areas where fuel vapors can collect. The lack of adequate ventilation may result in personal injury.

Caution: Always wear safety goggles when working with fuel in order to protect the eyes from fuel splash.

Notice: Do Not handle the fuel sender assembly by the fuel pipes. The amount of leverage generated by handling the fuel pipes could damage the joints.

Notice: Clean all of the following areas before performing any disconnections in order to avoid possible contamination in the system:

1. Relieve the fuel system fuel pressure. Refer to Fuel Pressure Relief in Engine Controls.
2. Drain the fuel tank (1) to at least 3/4 of a tank full. Refer to Fuel Tank Draining in Engine Controls.

Important: The modular fuel sender support assembly will spring-up when the locking ring is moved.

3. Remove the fuel sender assembly. Refer to Fuel Sender Assembly Replacement in Engine Controls.

1. Note the position of the fuel sender strainer for installation.
2. Support the reservoir with one hand and grasp the fuel sender strainer with the other hand.



3. Pull the external fuel sender strainer off of the fuel pump.
4. Inspect the fuel sender strainer. If the fuel sender strainer is contaminated, the fuel tank should be cleaned.
5. Discard the fuel sender strainer (1) after inspection.



6. Disassemble the electrical connectors from the sensor assembly of the fuel pump and the cover assembly.
7. Disassemble the fuel level sensor assembly.

1. Assemble the fuel level sensor assembly.
2. Assemble the electrical connectors to the fuel pump and the cover assembly.
3. Position the new fuel sender strainer (1) on the modular fuel sender and push on the outer edge of the fuel sender strainer until the fuel sender strainer is fully seated.

1. Install the fuel sender assembly. Refer to Fuel Sender Assembly Replacement in Engine Electrical.
2. Add fuel and install the fuel tank filler pipe cap.
3. Install the negative battery cable. Refer to Battery Cable in Engine Electrical.
4. Inspect for leaks.

4.1.	Turn the ignition switch to the On position for 2 seconds.

4.2.	Turn the ignition switch to the Off for 10 seconds.

4.3.	Turn the ignition switch to the On position.

4.4.	Visually inspect the fuel system for fuel leaks.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.




5. Install the fuel sender access panel.

Tighten
Tighten the bolts to 2 N·m (18 lb in).

6. Install the rear compartment floor trim. Refer to Rear Seat Cushion Replacement in Body and Accessories.
7. Install the spare tire, the jack, and the spare tire cover.
