Do not attempt to prise the plug from the regulator housing, or adjust the Allen screw (if no plug is fitted); this will alter the fuel system pressure.

3 Examine all components and renew any defective items as necessary Refitting
4 Commence reassembly by supporting the CFI unit on its side so that the regulator components can be fitted from above.

5 Fit the small spring, valve, diaphragm (ensuring that it locates correctly), large spring, and the spring cup.

6 Carefully place the ball into position on the spring cup, and ensure that it locates correctly.

7 Refit the regulator housing, taking great care to avoid disturbing the ball, and once correctly in position, tighten the screws evenly to avoid distorting the diaphragm.

8 Refit the CFI unit as described in Section 8.

9 On completion, the fuel system pressure should be checked by a Ford dealer at the earliest opportunity.
