6.5L DB2-4911 Injection Pump
GM/Stanadyne DB 6.5L
Remanufactured 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.
