1-15750151-1 (Reference No.: 105237-4731) is a genuine-quality hand primer pump assembly (manual fuel feed pump) designed for Isuzu 6WG1 series engines. This hand pump is installed on the fuel filter head or within the fuel line and is used to manually prime the fuel system before engine start-up, expelling trapped air and ensuring a steady fuel supply to the high-pressure fuel pump. It is an essential auxiliary component of the diesel engine fuel system.
The hand primer pump plays an irreplaceable role during fuel filter changes, fuel system maintenance, or restarting after running out of fuel. This unit is specifically engineered for Isuzu 6WG1 engines, offering easy operation and efficient priming.

OEM Quality: Manufactured to Isuzu technical standards for precise compatibility with 6WG1 engines.
Efficient Priming: Manual operation quickly establishes low-pressure fuel circuit pressure, effectively expelling air from the fuel system.
Easy Operation: Ergonomic design with smooth pressing action – no special tools required.
Reliable Sealing: High-quality sealing structure prevents fuel leakage and air ingress.
Direct Replacement: Standard OEM specification for hassle-free, bolt-on installation.
Broad Application: Fits HITACHI ZX series excavators, SUMITOMO excavators, Isuzu heavy trucks, and many other mainstream equipment brands.
Verify that the new hand primer pump matches the old unit (part number 1-15750151-1) before installation.
Ensure the sealing washer or O-ring is properly positioned for a good seal.
After installation, press the hand primer pump several times until firm resistance is felt, indicating that the fuel system is primed and air has been expelled.
Start the engine and check for any fuel leaks.
