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 mixtures 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 injection system with the engine

running. The fuel pressure within the system can be as high as 1650 bar. 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. Failure to follow this instruction may result in damage to the vehicle.

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

damage to the vehicle.

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 caps to any open orifices or

lines. Failure to follow this instruction may result in damage to the vehicle.

CAUTION: Do not remove the fuel rail pressure sensor from the fuel injection

diverter rail.

NOTE:

If a new fuel rail pressure sensor is to be installed, a new fuel injection diverter rail and
