Caution

CAUTION

Before doing any work on the components of the fuel supply system, proceed as follows to prevent dangerous leaks of fuel:

• Remove the protective cap and disconnect the fuel pump supply relay (1).

• Run the engine until it stops.

FUEL FILTER

The filter is inserted in the delivery pipe to the injectors, under the car floor next to the fuel tank.

It is formed of an outer aluminium casing and an inner polyurethane support which carries a paper element with high filtering power.

Filtering of the fuel is absolutely necessary to ensure correct functioning of the injectors as they are highly sensitive to foreign matter in the supply circuit.

An arrow on the outer casing of the filter points in the direction of the flow of the fuel, therefore the correct assembly position.

REPLACEMENT

• Set the car on a lift and raise it.

1. Slacken the fastening screws and remove the plastic cover to gain access to the fuel filter.

1. Disconnect the connections of the fuel inlet and outlet pipes from the filter (see "FUEL PIPE FITTINGS" - Boxer 18V engine)
2. Slacken the two screws fastening the suppor bracket, then remove it complete with fuel filter.

• Separate the fuel filter from the support bracket on the bench.

• Install the new filter so that the arrow stamped on it points in the direction of the flow of fuel.
