1985 Detroit Stanadyne DB2 Mechanical Injection Pump (DB2829-4425)
Description
Stanadyne DB2 mechanical injection pump for 1985 GM C/K 1500 and 2500 trucks running the 6.2L Detroit Diesel V8. OE-spec replacement for trucks that have lost fuel pressure, developed shaft seal leaks, or won't hold timing from a tired stock pump.
Bolts to the factory front cover, uses OE hard lines, lift pump connection, and shutoff solenoid. Calibrated to OE fuel rates — stock-power applications only.
Features
- Stanadyne DB2 Pump for 6.2L Detroit Diesel
- Calibrated to OE Spec
- Direct Bolt-On — Factory Lines & Mounting
- Mechanical Injection — No ECM or Electronics
- For Stock-Power Trucks
- Part Number: DB2829-4425
