Stanadyne DB2-5070 Diesel Injection Pump Data Plate - 1816350C91 Spec Tag

This is a photograph of the manufacturer's data/spec plate riveted to a Stanadyne fuel injection pump, taken in a dark engine bay. The plate identifies the pump maker as Stanadyne (marked 'PATENTED'), with the plant location shown as Windsor, CT, U.S.A. The stamped model designation reads 'DB2·5070', identifying it as a Stanadyne DB2-series rotary diesel injection pump. Two stamped number fields are visible in the lower band: '7584257' (in the field labeled SERIAL NO.) and '1816350C91' (in the field labeled MFG. NO.). From this plate a reader can determine the pump family (Stanadyne DB2), the specific calibration/model code (5070), the pump's serial number, and the manufacturing/customer part number, which is useful for ordering a replacement or rebuilt pump, matching calibration specs, or verifying the pump installed on the engine. No vehicle year, engine displacement, or application data is printed on the plate itself, so applicability must be determined from the model and manufacturing numbers.
