Removal Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: M.C.S. regulated engines are equipped with check valves which allow specific pressure sensors to be removed while the engine remains in operation.
Illustration 1 g03710683
Illustration 2 g03710682
Cut cable strap (3). Disconnect harness assembly (4) from primary filter base inlet fuel pressure sensor (2).
Remove primary filter base inlet fuel pressure sensor (2). Inspect check valve (1) for leaks. Replace as necessary. Refer to Disassembly and Assembly, "Check Valve - Remove and Install" for the correct removal and installation procedure.
Remove O-ring seal (5) from primary filter base inlet pressure sensor (2). Installation Procedure
Illustration 3 g03710682
Illustration 4 g03710683
Install a new O-ring seal (5) to primary filter base inlet pressure sensor (2).
Install the primary fuel filter base inlet pressure sensor (2) to the check valve (1). Tighten pressure sensor to a torque of 10 N m (89 lb in).
Connect harness assembly (4) to primary filter base inlet fuel pressure sensor (2). Install a new cable strap (3) to the harness assembly. Note: Ensure that the cable strap meets the Original Equipment Manufacture (OEM) specification.
