Fuel line High pressure - Remove (B.20.A.36.20 - F.10.A.10)
CX720, CX740, CX760, CX780, CX820, CX840
1. Removal
In the case of damage to a single fuel injection line,
do not attempt to remove it by itself. Always remove
the fuel injection lines as a set. It is much easier
to get them off the engine, and it helps to prevent
damaging the injection lines that are still good.
2. Remove the low-pressure fuel lines following the pro-
cedures described in Fuel line Low pressure - Re-
move (B.20.A.36.10 - F.10.A.10).
3. Disconnect the fuel injection lines at the injectors. As
the line is removed, use a plastic cap to prevent the
entry of dirt into the system.
4. Disconnect the fuel lines at the fuel injection pump
(3). Cap each line and pumping element as the line
is removed to prevent the entry of dirt into the system.
Use two wrenches on the lines to prevent accidental
rotation of the pumping element.
5. Detach the bracket (1) holding the fuel injection line
assembly to the intake manifold.
