The Replacement DC31450108 is an electric fuel transfer pump (also known as a lift pump or fuel feed pump) designed as a direct OEM replacement for 6.6L Duramax diesel-equipped Chevrolet Express and GMC Savana vans. This pump is responsible for supplying diesel fuel from the tank to the high-pressure injection system at the correct pressure and flow rate, helping to ensure reliable engine operation.

Key Features:

• Direct OEM replacement — designed to match original fit, form, and function
• Electric fuel transfer pump for 6.6L V8 Duramax diesel engines
• Replaces OEM part numbers: 15161174, 15821962, 23495127
• Maintains proper fuel pressure and flow rate demanded by the diesel injection system
• OE-matched electrical connections for straightforward installation
• Helps protect the high-pressure injection pump from excessive wear caused by fuel starvation

A functioning lift pump is critical on diesel applications — a failed or weak fuel transfer pump forces the high-pressure injection pump to draw fuel directly from the tank, significantly increasing wear and the risk of premature injection pump failure. Replacing a worn transfer pump promptly helps safeguard the entire fuel injection system.
