Tools Required

Caution: Gasoline or gasoline vapors are highly flammable. A fire could occur if an ignition source is present. Never drain or store gasoline or diesel fuel in an open container, due to the possibility of fire or explosion. Have a dry chemical (Class B) fire extinguisher nearby.

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

•	The fuel pipe connections

•	The hose connections

•	The areas surrounding the connections

Important: Position the fuel pressure gage fitting to avoid contact with the belt.

1. Install the J 34730-1A with the J 34730-262 to the fuel pressure service connection, located on the fuel rail.
2. Turn ON the ignition.

Caution: Do not drain the fuel into an open container. Never store the fuel in an open container due to the possibility of a fire or an explosion.

3. Place the bleed hose of the fuel pressure gage into an approved gasoline container.
4. Open the bleed valve on the fuel pressure gage in order to bleed the air from the fuel pressure gage.
5. Command the fuel pump ON with a scan tool until all of the air is bled out of the gage.
6. Close the bleed valve on the fuel pressure gage.
7. Command the fuel pump ON with a scan tool.

Caution: Wrap a shop towel around the fuel pressure connection in order to reduce the risk of fire and personal injury. The towel will absorb any fuel leakage that occurs during the connection of the fuel pressure gage. Place the towel in an approved container when the connection of the fuel pressure gage is complete.

8. Inspect for fuel leaks with the following procedure:

8.1.	Turn ON the ignition for 2 seconds.

8.2.	Turn OFF the ignition for 10 seconds.

8.3.	Turn ON the ignition.

8.4.	Inspect for fuel leaks.

1. Place the fuel pressure gage bleed hose into an approved container and open the bleed valve to bleed fuel system pressure.



2. Place a shop towel under the fuel pressure gage adaptor fitting to catch any remaining fuel spillage.
3. Remove the J 34730-1A from the adaptor fitting.
4. Remove the J 34730-262 .
5. Drain any fuel remaining in the fuel pressure gage into an approved container.
6. Install the cap on the fuel pressure connection.
