Industrial Injection 92-93 Chevrolet 6.5L HD C/K / P - Turbo (200 Hp) Mechanical Fuel Pump

The Industrial Injection DB2831-4911 is a remanufactured DB2 Stanadyne injection pump designed for 1992-1993 GM 6.5L Turbo Diesel pickup and van applications. It is marketed as a "Turbo 200 HP" pump, indicating a potential performance upgrade over the original equipment. A key improvement mentioned in the product description is the use of a steel sleeve in the advance bore. This addresses a common weakness in all-aluminum Stanadyne DB2 pump housings, which tend to wear out where the steel advance piston is located. This wear can lead to poor fuel mileage, excessive smoke, and low power. By utilizing a steel sleeve, the pump aims for more precise calibration and a longer lifespan. The pump comes with a one-year warranty.
