Fuel accumulator - removal and refitting

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

Pre-1986 models
Removal

2 Disconnect the battery negative lead.

3 Raise the rear of the car and support it on axle-stands (see “Jacking and Vehicle Support”).

4 Relieve the system pressure by slowly loosening the fuel feed pipe at the warm-up regulator. Absorb fuel leakage in a cloth.

5 Disconnect the fuel pipes from the fuel accumulator and catch the small quantity of fuel which will be released (see illustration).
