For 1990-2009 cars

### Installation Procedure

#### Tools Required

• | J 34730-1A Fuel Pressure Gauge.

• | J 34730-75 Fuel Rail Adapter.

1. Relieve the fuel pressure. Refer to Fuel Pressure Relief .
2. Remove the air cleaner (ACL). Refer to Air Cleaner Assembly Replacement .
3. Disconnect the hose clamp and the fuel feed hose from the throttle body. Use a shop towel to catch any remaining fuel that may leak.
4. Install the J 34730-75 Fuel Rail Adapter (2) to the throttle body fuel injection unit.
5. Connect the fuel feed hose (1) to the J 34730-75 Fuel Rail Adapter (2) and secure with the hose clamp.
6. Install the J 34730-1A Fuel Pressure Gauge (1) to the J 34730-75 Fuel Rail Adapter (2) and tighten securely.
7. Install the ACL. Refer to Air Cleaner Assembly Replacement .

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.

8. Connect the negative battery cable.

Tighten
Tighten the negative battery cable terminal retainer to 5.5 N·m (4 lb ft).

9. Start the engine.
10. Idle the engine at normal operating temperature.
11. Check the fuel pressure as follows:

• | 90-140 kPa (13-20 psi) with the engine idling.

• | 160-207 kPa (23-30 psi) with the engine not running and the ignition switch is ON -- FUEL PUMP IS RUNNING.

• | Fuel pressure should hold at or above 90 kPa (13 psi) within one minute of the engine not running while the ignition switch is ON -- FUEL PUMP IS NOT RUNNING.

12. If the fuel pressure is not within the specification, refer to Fuel System Diagnosis .
