Genuine SINOTRUK 201V12150-0002 hand oil pump for HOWO T7H, C7H & A7 trucks. OEM replacement for fuel system priming and lubrication.
When your SINOTRUK HOWO won’t start after changing the oil filter or replacing fuel lines, the problem isn’t always the injection pump — more often than not, it’s just air trapped in the system. That’s where the 201V12150-0002 hand oil pump comes in.
This genuine SINOTRUK hand-operated oil pump is a small but essential tool used across HOWO C7H, T7H, A7, and T5G models for manually priming engine oil circuits, bleeding fuel systems, or transferring fluids during maintenance. Whether you’re pre-lubing a rebuilt engine or getting a cold-start ready after winter storage, this compact pump delivers reliable performance without needing power or complex setup.
Built with a heavy-duty cast aluminum body and internal brass check valves, it handles both diesel fuel and engine oil with ease. The ergonomic lever design requires minimal effort, even under pressure, and the dual hose connectors (typically 6mm or 1/4″ NPT) fit standard SINOTRUK lines without adapters. Its rugged construction withstands drops, dust, and moisture — perfect for field use in remote mines, African depots, or roadside repairs in Southeast Asia.
Unlike plastic aftermarket copies that crack or leak, the original 201V12150-0002 maintains consistent suction and delivery, ensuring complete air removal and faster engine restarts. It’s also compatible with most common service kits and widely used by official SINOTRUK dealers during routine servicing.
We’ve seen too many drivers waste hours cranking engines because they skipped proper priming — or worse, damaged their pumps trying to bleed air with makeshift tools. This one works right the first time.

The 201V12150-0002 hand oil pump is typically used during engine startup after filter changes or fuel system repairs. Before installation, clean all port threads and inspect rubber gaskets — a damaged seal can cause air leaks and prevent proper priming. Connect inlet line from oil tank or fuel sump, outlet to the engine’s lubrication or fuel feed line. Mount securely using the two M8 bolts; vibration can loosen fittings over time. To prime the system, operate the lever slowly at first — around 40–60 strokes per minute — until resistance increases and fluid flows steadily. Avoid dry pumping. After use, close isolation valves and drain residual pressure if stored long-term. Lubricate the plunger O-ring annually with light grease to maintain smooth action and prevent sticking.
