FUEL SYSTEM - DEPRESSURISE
WARNING: Fuel pressure of up to 2.5 bar
will be present in the system, even if the
engine has not been run for some time.
Always depressurise the system before
disconnecting any components in the fuel feed
line (between fuel pump and pressure regulator).
The spilling of fuel is unavoidable during this
operation. Ensure that all necessary precautions
are taken to prevent fire and explosion.
NOTE: Fuel pressure can be relieved at
fuel rail feed union or fuel filter unions.
1. Position cloth around relevant union to protect
against fuel spray.
2. Carefully slacken union.
3. Tighten union to correct torque once pressure
has relieved.
