1994-2000 Detroit Diesel Rebuilt DS Injection Pump (DS4831-5521SE)

Industrial Injection rebuilt Stanadyne DS4 injection pump for 1994-2000 GM 6.5L Detroit Diesel trucks. The factory DS4 was the electronic-controlled successor to the DB2 and is a known weak point on the 6.5L platform — this is a fully rebuilt replacement, calibrated to OE spec and ready to bolt in.

Industrial Injection's pump shop has been rebuilding Stanadyne pumps for decades. Comes with a 1-year parts-only warranty.

• Rebuilt Stanadyne DS4 Electronic Injection Pump
• Calibrated to OE Spec for 1994-2000 GM 6.5L Detroit Diesel
• 1-Year Parts-Only Warranty
• Part Number: DS4831-5521SE

• IMPORTANT — Core must be sent first. Industrial Injection rebuilds your core; the pump does not ship until your core is received and inspected.
• Verify your pump tag on 1994 applications. If your existing pump tag reads DS4831-5068, it is NOT compatible with the DS4831-5521 — that is a different service-replacement number.
