Industrial Injection DB2-4520SE Remanufactured Stanadyne DB2 Injection Pump 6.2L GM CUCV Military

The Industrial Injection DB2-4520SE is a professionally remanufactured Stanadyne DB2 mechanical diesel injection pump engineered for the 6.2L GM CUCV (Commercial Utility Cargo Vehicle) military platform. This is a direct replacement for OEM pump numbers DB2829-4520 and 23500413, built to restore reliable fuel delivery and performance to your diesel powertrain.

Key Features:

• Remanufactured Stanadyne DB2 mechanical injection pump for the 6.2L GM military diesel
• Designed specifically for CUCV military applications (M1008, M1009, and related variants)
• Replaces OEM numbers: DB2829-4520, 23500413
• Calibrated to factory specifications for proper fuel timing and delivery
• Addresses the common advance bore wear issue found in original aluminum-housing DB2 pumps
• Precision-tested prior to shipment to ensure reliable performance

A common failure point on the Stanadyne DB2 platform is the advance bore, where the aluminum pump housing tends to wear prematurely around the steel advance piston. This wear leads to excess fuel return, poor pump timing, increased exhaust smoke, reduced fuel economy, and loss of power. Industrial Injection's remanufacturing process addresses these known weaknesses to deliver a unit that meets or exceeds original factory performance standards.

Core Charge Notice: A $300 refundable core charge applies to this purchase. The original pump must be returned in rebuildable condition to receive a full core refund.
