    Q:
    How to remove and install the engine covers, fuel rail Fuel Pressure Sensor, and high-pressure fuel pump on Chevrolet Express? Posted by Constance B.
    A:
    To remove the engine covers, relieve the fuel system pressure, and disconnect the cable from the negative battery terminal. Then, remove the intake manifold and the fuel pump/fuel rail insulator. For the fuel rail fuel pressure sensor, disconnect the electrical connector and unscrew the sensor from the end of the fuel rail. Clean the threads and apply oil to the new sensor before installing it. Tighten the sensor to the proper torque specifications and reconnect the electrical connector. The installation process is the reverse of removal. To remove the high-pressure fuel pump, disconnect the low-pressure feed line and unscrew the high-pressure line fittings. Disconnect the electrical connector and remove the pump bolts, cover, and gasket. Replace the bolts and gasket with new ones. Ensure the camshaft lobe is at its base circle before installing the pump and lubricate the pump roller with engine oil. The installation process is the reverse of removal. Clean the high-pressure fuel line fittings, apply oil to the threads, and install the new high-pressure fuel line. Finally, reconnect the cable to the negative battery terminal, start the engine, and check for fuel leaks.
