Fuel pressure regulator - removal and refitting

Note: Refer to the precautions at the end of Section 1 before proceeding.

Removal
1 The fuel pressure regulator is only used on KE-Jetronic systems and is located behind the fuel distributor (see illustration).

2 Disconnect the battery negative lead.

3 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.

4 Place absorbent cloth beneath the regulator and undo the two fuel feed unions and the fuel return union. Note the pipe locations to ensure correct refitting.

5 Remove the securing tie and withdraw the regulator from its bracket.

Refitting
6 Refitting is a reversal of removal. Ensure that all unions are correctly reconnected and secure, and on completion check for fuel leaks with the engine running (see illustration).
