Product Title
1-15750130-0 / 105237-4421 Hand Primer Pump for Isuzu 6HK1 Direct Injection Engine (Zexel)
Product Overview
This hand primer pump is specially designed for the Isuzu 6HK1 direct injection engine, with part number 1-15750130-0 and Zexel number 105237-4421. The hand primer pump (also known as a manual fuel feed pump) is an important auxiliary component of the fuel supply system. It is used to manually pump fuel after fuel filter replacement, fuel line bleeding, or during initial start-up, drawing fuel from the tank and filling the filter and high pressure pump while expelling air from the lines. Featuring a precision plunger and check valve design, it offers high pumping efficiency and easy operation – an essential component for reliable engine starting.
Key Features
Precision plunger design – Plunger components are high-precision machined with controlled clearances for stable pumping pressure and reliable sealing.
High-efficiency check valves – Built-in inlet and outlet check valves prevent fuel backflow, ensuring effective pumping action.
Ergonomic handle – Handle design conforms to natural operating posture for easy pumping with minimal effort.
Oil and corrosion-resistant – Housing and seals made of diesel-resistant, corrosion-resistant materials suitable for various fuel qualities.
OEM specifications – Manufactured to Isuzu/Zexel original technical standards, with mounting dimensions fully compatible with original units.

Installation & Usage Tips
Before installation, verify the part number (1-15750130-0) and Zexel number (105237-4421) match your original unit.
Pay attention to the inlet and outlet port orientation during installation – do not reverse connections (flow direction is typically marked on the pump body with an arrow).
After installation, press the primer handle several times until resistance noticeably increases, indicating that fuel has filled the lines and filter.
If resistance remains low or pumping is weak after prolonged operation, check for fuel line blockages or air leaks.
It is recommended to use the hand primer pump to bleed air after every fuel filter replacement to ensure smooth starting.
