Removal/Installation

INSTALLATION

(1)Ensure fuel pressure regulator has two plastic spacers (Fig. 16). Place O-rings in the fuel pressure regulator cavity (Fig. 17). Do not install O-rings on the fuel pressure regulator.

(2)Insert fuel pressure regulator into the fuel rail.

(3)Install fuel pressure regulator retainer (Fig. 15).

(4)Install retainer screw. Tighten to 7 NIm (60 in. lbs.) torque.

(5)Connect vacuum line to the fuel pressure regu-

lator.

CAUTION: When using the ASD Fuel System Test, the Auto Shutdown (ASD) Relay remains energized for either 7 minutes, until the test is stopped, or until the ignition switch is turned to the Off position.

(6) With the ignition key in ON position, access the DRB II ASD Fuel System Test to pressurize the fuel system. Check for leaks.

FUEL INJECTOR

The fuel rail must be removed first. Refer to Fuel Injector Rail Assembly Removal in this section.

REMOVAL

(1)Disconnect injector wiring connector from injec-

tor.

(2)Position fuel rail assembly so that the fuel injectors are easily accessible (Fig. 18).

(3)Rotate injector and pull injector out of fuel rail. The clip will stay on the injector.

(4)Check injector O-ring for damage. If O-ring is damaged, it must be replaced. If injector is reused, a protective cap must be installed on the injector tip to prevent damage. Replace the injector clip if it is damaged.

(5)Repeat for remaining injectors.
