5.6 REMOVAL AND INSTALLATION, HIGH-PRESSURE PUMP
When removing the high-pressure
pump, fuel will escape. Collect the
fuel and avoid the risk of fire.
Dirt in the fuel system can lead to
significant damage to parts of the
system. Prevent this by cleaning the
parts before disassembly and then
sealing all open connections.
Removing the high-pressure pump
1. Clean the high-pressure pump and that part
of the engine around it thoroughly with, for
example, a steam cleaner. Cover the places
at which leaks have been detected to
prevent dirt getting into the fuel system.
2. Disconnect the fuel pipes from the high-
pressure pump. Loosen the return pipe only
on the high-pressure pump.
3. If fitted, uncouple the connector of the fuel
temperature sensor (1) on the fuel fine filter
head and the connector of the fuel pump
control solenoid valve (2).
4. Remove the fuel fine filter together with the
filter head.
5. Loosen both unions from the high-pressure
pipe to the fuel rail as well as the pipe
clamps. Remove the high-pressure pipe.
Plug all openings.
6. Remove the three high-pressure pump
attachment nuts and then the high-pressure
pump.
