Removal Procedure
- Relieve the fuel system pressure. Refer to Fuel Pressure Relief (Without CH-48027) , Fuel Pressure Relief (CH-48027) , Fuel Pressure Relief (High Side) .
- Remove the intake manifold. Refer to Intake Manifold Replacement
- Remove the foam insulator from the fuel rails.
- Disconnect the fuel pressure sensor electrical connector.
- Using a 27 mm socket, remove the fuel pressure sensor (1) from the fuel injection fuel rail (2). Discard the fuel pressure sensor.
- Allow any fuel to drain from the fuel rail and pressure sensor location.
- Dry the sealing cone in the fuel rail and the area around the sensor joint with a lint free cloth.
- Inspect the sealing cone in the fuel rail. The surface should be free of fuel, debris, and burrs.
CAUTION:
To avoid fuel system contamination clean the area where the sensor connects to the fuel line or fuel injection fuel rail before removing the sensor.
NOTE:
Applying force to the plastic housing of the sensor will destroy the sensor. To tighten or loosen, only apply force to the attached hexagon.
