Remove the fuel filter bracket together with the fuel fitter.

10 Remove the high pressure fuel pipes. Where a Bosch fuel injection pump is fitted, ensure that a separate spanner is used to prevent movement of the fuel injection pump outlets when the connections of the high pressure pipes are released. Fit suitable covers to all open connections on the fuel injection pump.
