Description Remanufactured Stanadyne DB2 mechanical injection pump (DB2-5088SE) for 1994-1997 Chevrolet/GMC G-series vans running the 6.5L Detroit Diesel. Direct OE-spec replacement for stock-power van applications. Each pump is fully torn down, inspected, and rebuilt with new wear parts before being flow-tested on a Stanadyne stand against OE spec. Bolts to the factory front cover, uses OE hard lines and shutoff solenoid. The 6.5L Detroit Diesel was Chevrolet/GMC's diesel engine for vans, light commercial trucks, and HD pickups before the Duramax arrived in 2001.
