Due to popular demand we now offer high performance GM DB2 builds, these pumps require no core charge and are built with all new components. Just as in our 130cc and larger Ford db2s, all of these pumps feature locked timing and a flat fuel curve, as well as the option to add our ICFC.

Current lead time for Custom GM injection pumps is 10-12+ weeks depending on parts availability! 

This pump is available with our proprietary In-Cab-Fueling-Controller (ICFC), which allows adjustment from inside the cab of total fueling (max power) as well as how aggressive the injection pump fuels (smoke control). This is done completely pneumatically, with no fuel plumbed into the cab, or any electronic controls to complicate the simplicity of mechanical injection.

All Classic Diesel Designs' DB2 injection pumps are built to and exceed oem specification. All pumps are built with a new advance piston, balanced metering valve to reduce side load and stickage issues, low lubricity spec tool steel blade set and transfer pump liner to reduce wear with modern dry diesel, high torque shutoff solenoid, viton material grade seals, updated delivery valve, delivery valve stop, and low lubricity grooved plungers.

See Stanadyne service bulletins: S.B 60R8, S.B.108RlO, S.B.125R5, S.B. 304R8 S.B. 334R1, S.B. 373R1.

A common issue with the design of the DB series rotary pump is rapid wear of the advance piston bore due to the hardened piston sliding in the aluminum bore quickly eroding the critical tolerance due to lack of lubricity of modern diesel fuel. Most cheaper rebuilds ream out this bore and fit a larger piston, but this is just a temporary fix and soon the hydraulic advance will be out of spec, resulting in a lack of power, high egts and a smokey exhaust.Our solution is to mill out this bore and install a ceramic sleeve. This ceramic sleeve allows us to create a better fit than with the original design, and shows no wear after over 100k miles, extending the lifespan of the pump, and maintaining the same out of box performance many years down the road.
