INSTALLATION WARNING: THE FUEL PRESSURE REGULATOR, (1) Lubricate new O-ring with a drop of clean en- gine oil. Install spacer and O-ring into the receiver (2) Install mounting nuts. Tighten nuts to 7 N Im (65 in. lbs.) torque. (3) Connect fuel return tube to pressure regulator. Using a wrench to hold the fuel pressure regulator, Im (150 in. lbs.) torque. (4) Connect vacuum hose to pressure regulator. Re- place clamp. (5) Connect negative cable to battery. CAUTION: When using the ASD Fuel System Test, (6) With the DRBII scan tool, use the ASD Fuel System Test to pressurize system and check for MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR (1) Remove vacuum hose and remove mounting screws from sensor (Fig. 14). (2) Remove wiring harness and remove sensor. PCM SERVICE (1) Remove air cleaner duct from PCM. and remove module. (5) Reverse the above procedure for installation.
