Pump model Identification
To Identify the pump model # one simply needs to access the serial number tag.
Shown above is a DS-4 electronic pump. The key numbers we are looking for is the 5521. This dictates that it is the latest (5521) pump available.
Potential numbers are: 5067, 5068, 5288, 5459, and 5521. Pump model ID is critical for computer chip selection as the 5068 pump is unique. All others will interchange, but the 5068 requires a different program on the ECM chip. In order to view this tag one must remove the upper intake casting and often use a mirror.
The lower photo is a DB2 Mechanical pump. The key numbers once again are in the Upper left blank of the ID tag. The model shown is a 4911.
