Description

Product Overview

Part number 4945792 is Weifu mechanical inline fuel injection pump, OEM matching assembly for Cummins 6L 300HP and ISDE Euro II diesel engines, interchangeable with 4944883, 4945791, 5342391.

This pump provides stable high-pressure diesel fuel for injectors of heavy-duty trucks, passenger coaches, engineering machinery and generator sets. Worn internal plunger, valve or pump body will cause hard cold start, insufficient climbing power, unstable idle, black smoke and fuel leakage. Our finished pump undergoes full bench calibration before shipment to restore original engine fuel supply performance.

Common Faults Solved By Replacing 4945792 Injection Pump

Difficult cold start, long cranking time to ignite engine
Weak acceleration & insufficient climbing power under heavy load
Rough idle speed and obvious engine shaking
Thick black smoke emission during acceleration
External fuel leakage at pump joint surface, rising fuel consumption
