1991-1993 6.2 LD Chevy/GMC Diesel Injection Pump for GM 6.2L Light Duty Diesel Engines DB2829-5056
In 1982 General Motors introduced the 6.2L diesel engine. It replaced the Oldsmobile 5.7L diesel. The engine was designed to be a more fuel efficient option to the gas engines of the time. The 6.2 diesel engine was manufactured by Detroit Diesel (a division of General Motors) with economy as the goal not power and torque. Horsepower numbers started at 130 HP @ 3600 rpm and peaked at 143 HP @ 3600 rpm. Torque ranged from 240 lb-ft @ 2000 rpm to 257 lb-ft @ 2000 rpm. A military version produced 165 hp @ 3600 rpm and 330 lb-ft @ 2100 rpm.
Through the years there were many different variations in the 6.2 diesel injection pumps. The engine application codes were based off the Truck Style, Model Designation, and if the engine was equipped with or without a turbocharger.
This pump will work on the following applications. Due to minor differences this pump may not be a direct supersession, but will work properly. If you want your pump built to a specific model code, Huckstorf Diesel will be happy to do that for you. If you want to have your pump customized for a performance application we can do that also. Give us a call and we can discuss your options!
