Replacing the PS8500 fuel pump is serious work — always relieve fuel pressure before starting. Disconnect the battery and drain excess diesel from the rail if possible. Remove fuel lines carefully using copper washers; inspect for cracks or hardening. Mark the timing gear position before removing the old pump — even a single tooth off can cause hard starts or black smoke. Install the new VG1560080023 unit with fresh mounting bolts and align the drive coupling precisely. Torque injector lines to 25–30 Nm and prime the system using the hand primer pump or electric lift pump. Bleed air from the filter housing first, then crank the engine without starting for 10 seconds to build pressure. Once running, check for leaks immediately — diesel under pressure is a fire hazard. Use a diagnostic tool to confirm no fault codes appear. Run at idle for 5 minutes before loading.
