Remanufactured DB2 Injection Pump
GM/Stanadyne DB 6.5L Fuel Injection Pump
These pumps go through a thorough re-manufacturing process and get re-assembled to OE specifications. Components are completely cleaned, inspected, and tested. Worn or damaged components are replaced with new to ensure maximum quality and longevity. All of our re-manufactured DB pumps feature the updated head and rotor to combat hot-start issues and an anodized advance piston sleeve to address metal-on-metal wear in the advance bore. If you want to do it once and do it right, then this is the replacement pump for you.
The pump is tested as a full assembly before being shipped to install on your vehicle. You must move the throttle position sensor (TPS) from your old pump to this one before installing.
- Updated head and rotor. We never re-use inferior core to reduce costs
- Upgraded, anodized advance piston sleeve
- Fully tested and calibrated to OE 4911 pump 6.5L turbo spec
- Built and tested in the USA by a Stanadyne certified tech. Pump will have the proper red Stanadyne ID tag and serial number to reflect this.
CORE DEPOSIT REQUIRED unless you contact us about sending your pump core in ahead of time.
