Removal Procedure
- Remove the common rail assembly. Refer to Fuel Injection Fuel Rail Assembly Replacement .
- Clean interface area of the rail pressure sensor using proper degreases materials and compressed air for drying.
- Remove the rail pressure sensor with the gasket if equipped.
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:
• Use care when servicing the fuel system components, especially
the fuel injector electrical connectors, the fuel injector tips, and
the injector O-rings. Plug the inlet and the outlet ports of the fuel rail
in order to prevent contamination. • Do not use compressed air to clean the fuel rail assembly as this
may damage the fuel rail components. • Do not immerse the fuel rail assembly in a solvent bath in order
to prevent damage to the fuel rail assembly.
Installation Procedure
- Inspect and clean the thread and the sealing surface of the rail.
- Inspect and clean the thread and rail pressure sensor (1).
- Lubricate thread and bite edge (2) of the rail pressure sensor using lubricant Ft1v27, only apply a thin lubrication film.
- Install the rail pressure sensor to the common rail.
- Prime the fuel system. Refer to Fuel System Priming .
Notice: Refer to Fastener Notice in the Preface section.
Tighten
Tighten the rail pressure sensor to 70 N·m (51.6 lb ft).
