Removing
Warnings:
- Some fuel will inevitably spill during this operation. Ensure that all necessary precautions have been taken to prevent fire and explosion.
- Do not carry or use a cell phone while working on or in the vicinity of any fuel related items. There is a danger of ignition of flammable vapours. Failure to follow these instructions may result in injury.
- Do not smoke or walk with a lit cigarette or any type of open flame while working on or near fuel related items. There is a danger of ignition of flammable vapours. Failure to follow these instructions may result in injury.
- If fuel gets in your eyes, rinse them with cold water or special eyewash solution and seek immediate medical attention.
- Wash your hands thoroughly after handling fuel as prolonged skin contact with fuel may cause irritation. Seek medical attention if irritation occurs.
- Do not carry out any repairs to the fuel system while the engine is running. The fuel pressure in the system can reach 2000 bar. Failure to follow this instruction may result in injury.
CAUTION: Diesel fuel injection equipment is manufactured to very precise tolerances and very close clearances. Therefore, when working with these nodes, absolute cleanliness is required. Be sure to install new plugs in all open holes and piping. Failure to follow this instruction may lead to the penetration of dirt into the fuel injection system.
1. Disconnect the wire "masses" from the battery.
For more information, see the chapter: Disconnecting and connecting the battery (414-01 Battery, Battery Mount and Wires, General Procedures).
2. Using a vacuum cleaner, remove foreign material from the high pressure fuel supply lines, fuel manifolds and high pressure fuel pump.
For more information, refer to the chapter: Cleaning the fuel injection system components (303-04A Fuel Supply and Controls - ID4 2.4L Diesel Engine, General Procedures).
3. Remove the connecting sleeve.
4. Remove and discard the fuel relief valve.
5.
CAUTION: Check that the fuel rail mating surfaces are not damaged. Failure to follow this instruction may result in damage to the elements.
Remove the gasket and send it for recycling.
Installation
1.
CAUTION: Check that the fuel rail mating surfaces are not damaged. Failure to follow this instruction may result in damage to the elements.
Install a new gasket. Clean the contact surfaces of the parts.
2. Install a new fuel rail pressure relief valve. Tighten (tightening torque 30 Nm).
3. Draw a line on the corner of the fuel relief valve (1) and on the side of the fuel manifold (2).
4. Draw a line (3) 3 mm from the line (2)
5. Tighten the fuel relief valve and make sure line 1 aligns with line 3. Tighten (tightening torque 172 Nm).
6. If line (1) does not line up (3), remove the fuel relief valve and inspect it for contamination and damage to the fuel rail connection threads. Carry out the assembly starting from point 2.
7.
NOTE: Remove and discard plugs.
Install the connecting fitting.
- Clean the contact surfaces of the parts.
- Tighten (tightening torque 20 Nm).
8. Connect the wire "masses" to the battery.
For more information, see the chapter: Connecting the Battery (414-01 Battery, Battery Mount and Wires, General Procedures).
9. Check the fuel system for leaks using the Land Rover approved diagnostic system.
