The Fuel Feed Pump (Low-Pressure Supply Pump) with OEM numbers 105220-5960 and 105220-5001 is a verified OEM-grade replacement for Komatsu excavators and compatible diesel engines. Manufactured to Denso OEM specifications, this mechanical pump is a critical component of the diesel fuel system, responsible for drawing fuel from the tank and supplying it at the correct low pressure to the high-pressure injection pump.
✓OEM Specification - Verified by multiple OEM part numbers: 105220-5960, 105220-5001, DK105220-5960, 1052205960, 1052205001
✓Proven Durability - Built with wear-resistant materials to withstand continuous heavy-duty operation
✓Installation Success Rate - 99% direct bolt-on fitment for compatible Komatsu excavator models
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 due to insufficient fuel pressure
Loss of Engine Power: Significant reduction in power and acceleration, especially under load
Engine Stalling / Rough Running: Intermittent stalling or rough idle due to inconsistent fuel supply
Frequent Need for Priming: Pump does not build sufficient pressure, requiring frequent air bleeding
Visible Fuel Leakage: Fuel seeping from the pump body indicating 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.
