1990 Detroit Stanadyne DB2 Mechanical Injection Pump (DB2829-4779)

Stanadyne DB2 mechanical injection pump (DB2829-4779) for the 1990 GM 6.2L Detroit Diesel found in Chevrolet/GMC C/K trucks, G-series vans, and P30/P3500 chassis. Direct OE-spec replacement calibrated for the factory power level on these stock or lightly-modified rigs.

The DB2 is a rotary distributor pump originally calibrated by Stanadyne for the GM 6.2L Detroit Diesel platform — predecessor to the 6.5L Detroit and the Duramax. Each unit ships ready to bolt back on: fuel rates, advance, and shutoff are all set to OE spec. Uses factory hard lines, lift pump, and timing reference.
