Warm-up regulator - removal and refitting

Note: Refer to the precautions at the end of Section 1 before proceeding. New banjo union sealing washers must be used on refitting.

Removal
1 The warm-up regulator is only used on KJetronic systems and is situated on the inlet manifold just to the rear of the rocker cover.

2 Disconnect the battery negative lead.

3 Relieve the system pressure by slowly loosening the fuel feed pipe union at the warm-up regulator (see illustration 6.3).

Absorb the fuel leakage in a cloth.

4 After relieving the system pressure disconnect the fuel feed union completely, followed by the outlet union. Recover the sealing washers used on each side of the unions.

5 Disconnect the regulator wiring multi-plug.

6 Undo the two Torx type screws using a suitable Torx key or socket bit and remove the regulator from its location (see illustration).

Refitting 7 Refitting is a reversal of removal, but use new sealing washers on each side of the banjo unions and apply a thread-locking compound to the Torx retaining bolts. On completion check for leaks with the engine running.
