Genuine OEM and High-Performance Fuel Transfer Pump for Caterpillar | Part 7N-6831 & 279-4980

Maintain the fuel system integrity of your heavy equipment with this high-performance fuel transfer pump, specifically engineered for Caterpillar 3304 and 3306 engines. Both part numbers 7N-6831 and 279-4980 are interchangeable and serve as the primary pump responsible for pulling fuel from the tank and delivering it under constant pressure to the injection pump.

Built to withstand the high-vibration and extreme pressure environments of heavy-duty construction, this pump features a ruggedized cast housing and precision-machined internal valves to prevent pressure drops and fuel starvation. It is a direct fit for a wide range of Caterpillar machinery, including the 235 excavator, 973 track loader, and 950B wheel loader. Replacing a failing pump is critical for preventing engine stalling, hard starting, and power loss during high-load operations.
