Electro-magnetic pressure actuator - removal and refitting

~1min read
Note: Refer to the precautions at the end of Section 1 before proceeding. New O-rings must be used on refitting. Removal
1 The electro-magnetic pressure actuator is only used on KE-Jetronic systems and is located on the side of the fuel distributor. 2 Disconnect the battery negative lead. 3 Remove the air cleaner as described in Section 2. 4 Relieve the system pressure by slowly loosening the cold start valve union on the top of the fuel distributor (see illustration 6.4). Absorb fuel leakage in a cloth.

5 Disconnect the wiring multi-plug, then undo the two screws securing the actuator to the fuel distributor (see illustration). Remove the unit and the sealing O-rings.

Refitting 6 Refitting is the reverse sequence to removal, but ensure both mating faces are clean. New O-rings must be used and care taken not to displace them when fitting. On completion check for fuel leaks with the engine running.
