For 1990-2009 cars

### Installation Procedure

#### Tools Required

• | J 34730-1A Fuel Pressure Gauge.

• | J 42982 Fuel Pressure Gauge Adapter.

• | J 43178 Prizm Fuel Line Quick Connect Separator.

1. Relieve the fuel pressure. Refer to Fuel Pressure Relief .
2. Remove the fuel feed hose quick connect coupling cover.
3. Disconnect the fuel feed hose quick connect coupling from the fuel feed pipe of the fuel rail using the J 43178 Prizm Fuel Line Quick Connect Separator. Use a shop towel to catch any remaining fuel that may leak. Refer to Metal Collar Quick Connect Fitting Service .
4. Install the J 42982 Fuel Pressure Gauge Adapter between the fuel feed pipe of fuel rail and the fuel feed hose.
5. Install the J 34730-1A Fuel Pressure Gauge (1) to the J 42982 Fuel Pressure Gauge Adapter (2) and tighten securely.

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.

6. Connect the negative battery cable.

Tighten
Tighten the negative battery cable terminal retainer to 15 N·m (11 lb ft).

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

• | 301-347 kPa (44-50 psi) with the engine idling.

• | 301-347 kPa (44-50 psi) with the engine not running and the ignition switch is ON - FUEL PUMP IS RUNNING.

• | Fuel pressure should hold at or above 147 kPa (21 psi) within five minutes of the engine not running while the ignition switch is ON - FUEL PUMP IS NOT RUNNING.

10. If the fuel pressure is not within the specifications, refer to Fuel System Diagnosis .

### Removal Procedure
