WARNING: Wait at least 30 seconds after the engine stops before commencing any repair to the high-
pressure fuel injection system. Failure to follow this instruction may result in personal injury.
WARNING: Do not smoke or carry lighted tobacco or open flame of any type when working on or near
any fuel related components. Highly flammable vapors are always present and may ignite. Failure to follow
these instructions may result in personal injury.
WARNING: This procedure involves fuel handling. Be prepared for fuel spillage at all times and always
observe fuel handling precautions. Failure to follow these instructions may result in personal injury.
WARNING: Do not carry out any repairs to the fuel system with the engine running. The fuel pressure
within the system can be as high as 1650 bar (23,931 lb-sq-in). Failure to follow this instruction may result in
personal injury.
CAUTION: Make sure the workshop area in which the vehicle is being worked on is as clean and as dust
free as possible. Foreign matter from work on clutches, brakes or from machining or welding operations can
contaminate the fuel system and may result in later malfunction.
CAUTION: Always carry out the cleaning process before carrying out any repairs to the fuel injection
system components. Failure to follow this instruction may result in foreign matter ingress to the fuel injection
system.
CAUTION: Diesel fuel injection equipment is manufactured to very precise tolerances and fine
clearances. It is therefore essential that absolute cleanliness is observed when working with these components.
Always install blanking plugs to any open orifices or lines. Failure to follow this instruction may result in foreign
matter ingress to the fuel injection system.
CAUTION: Do not remove the FRP sensor from the fuel injection diverter rail.
If a new fuel rail pressure sensor is to be installed, a new FRP sensor and fuel injection diverter rail must be
installed as an assembly.
