• Take the fuel pipe with the four pre-mounted clips (1) from the kit and fit it to the sub-frame. Insert it between the loosened pipes and the sub-frame. Press it into place with the clips in the sub-frames front edge and in the bottom on the clips (2) holding the plastic hose in place. The space is tight, so the fuel pipe must be bent and twisted to get it into place.

• Refit the power steering pipes and press the plastic hose into place on the outside of the fuel pipe. Refit the rubber-coated clamp if it was removed.
• Check that the fuel pipe does not catch on the sub-frame. Ensure that the fuel pipe does not rub against pipes or screw heads for the suspension.

• Insert the end of the short fuel pipe, which is bent in two places, under the power steering servo and the anti-roll bar, on top of the right rear corner on the sub-frame.

• Take a hose clamp from the kit. Thread the hose clamp onto the short fuel line on the fuel pipe on the sub-frame.
• Connect the short fuel pipe to the fuel line. Slide the pipe into the fuel line. Slide the pipe in so that the two pipes are in contact with each other. This prevents air pockets from forming.
• Squeeze the hose clamp together.

Illustration A

• Remove the induction pipe and put it aside.

• Undo the hose clamp and detach the hose (1) from the air filter.

Примечание: If the hose is plastic, the hose joint will need to be carefully heated to release the hose. Use a hot-air gun.
- Pull the air filter from its mounting in the left front member and left wing liner.
- Unscrew the plastic nut (2) in the wing liner. It will be re-used.
- Move aside the air filter from the gearbox by tying it up with a string or the like. Depending on its design, several hoses or connectors may need to be disconnected around the air filter.

• Undo the quick-release connector on the cabin heater's left heater hose (1): Hold in the circlip of the quick-release connector in front of the two arrow tips while turning the circlip in the direction of the arrow. Turn the quick-release connector slightly and pull it out.
