The Fuel Feed Priming Pump with OEM numbers 1-15761006-1 (also listed as 1157610061) is a verified OEM-grade direct replacement for a wide range of ISUZU commercial vehicles and equipment, including the FVR34 truck series equipped with the 6HK1 diesel engine. As a critical component of the fuel system, this mechanical priming pump draws diesel fuel from the tank and delivers it to the high-pressure injection pump, ensuring a consistent, air-free fuel supply for optimal engine combustion and reliable power delivery.
Key Specifications:
OEM Specification — Verified by ISUZU OEM part numbers 1-15761006-1, 1157610061, and cross-references 1-15761006-0 and 1157610060
Proven Durability — Constructed from high-grade cast iron with precision-engineered internal components — rated for 300,000+ km under normal operation
Broad Compatibility — Fits ISUZU FVR34, FSR, NPR, CXZ trucks and ZX/ZAX series excavators with 6HK1, 6BD1, 6BG1 engines
Installation Success Rate — 99% direct bolt-on fitment with factory-style connections
Failure Symptoms
If your fuel feed pump is failing, you may experience one or more of the following symptoms:
Hard Starting / Extended Cranking: Engine takes longer than normal to start, especially after sitting
Loss of Engine Power: Significant reduction in power and acceleration, especially under load
Engine Surging or Stalling: Intermittent surging or stalling due to inconsistent fuel delivery
Frequent Need for Priming: The priming pump does not build sufficient firmness, or you frequently need to bleed air from the fuel system
Visible Fuel Leakage: Fuel seeping from the pump body — indicates worn internal seals
⚠️ Important: A failing fuel feed pump can lead to progressive power loss, engine stalling, and costly injection pump damage — prompt replacement is essential to maintain fuel system integrity and engine reliability.
