Genuine SINOTRUK VG1560080023 PS8500 fuel pump for HOWO T7H, C7H & A7 trucks. OEM replacement for MC11/MC13 engines.
When your HOWO truck starts hesitating under load, smoking heavily, or refuses to start after sitting overnight, don’t assume it’s the injectors — more often than not, the real issue lies deeper: ال fuel injection pump, specifically the PS8500 model (VG1560080023) used across SINOTRUK’s MC11 and MC13 engine platforms.
This genuine SINOTRUK PS8500 fuel pump isn’t just a part — it’s the heart of your diesel delivery system. Responsible for generating up to 1,800 bar of injection pressure, it ensures precise fuel metering and optimal combustion timing, directly affecting power output, fuel economy, and emissions compliance.

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.
