J 34730-1A Fuel Pressure Gauge

Caution: Place a dry chemical (Class B) fire extinguisher nearby before performing any on-vehicle service procedures. Failure to follow these precautions may result in personal injury.

1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief .

Caution: Provide additional support when a vehicle is on a hoist:

•	Before removing parts, support the opposite end. This helps prevent the vehicle from slipping off.

•	Before removing major components, chain the vehicle frame to the hoist pads at the same end as the removal. This helps avoid a tip-off.

Failure to follow these precautions could cause vehicle damage, serious personal injury, or death.
2. Raise the vehicle.



3. Remove the in-line fuel filter bracket.
4. Grasp the in- fuel filter and one fuel pipe fitting.



5. Twist quick-connect fitting 1/4 turn in each direction to loosen any dirt within fitting.
6. Repeat for other fuel pipe fitting.




Caution: Wear safety glasses when using compressed air in order to prevent eye injury.

Caution: To reduce the risk of fire and personal injury, before installing a new filter, always apply a few drops of clean engine oil to both pipe ends of the filter. This will ensure proper re-connection and prevent a possible fuel leak. (During normal operation, the O-rings located in the female connector will swell and may prevent proper re-connection if not lubricated).
