### Relief Procedure

#### Tools Required

• | J 34730-1A Fuel Pressure Gauge

• | J 34730-262 Fuel Pressure Gauge Fitting

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery terminal.

Important: Mount the fuel pressure gauge fitting above the belt to avoid contact with the belt.

2. Install the J 34730-262 Fuel Pressure Gauge Fitting adaptor to the fuel pressure connection.
3. Connect Fuel Pressure Gauge J 34730-1A to the fuel adaptor pressure fitting. Wrap a shop towel around the fuel pressure connection while connecting the fuel pressure gauge in order to avoid spillage.
4. Install the bleed hose into an approved container and open the valve to bleed the system pressure. The fuel connections are now safe for servicing.
5. Drain any fuel remaining in the fuel pressure gauge into an approved container.
