Our factory trained and certified technicians have been rebuilding DB2 automotive injection pumps since they were introduced by Stanadyne in the late 70's.

The DB2 injection pump is a reliable unit that was based on a proven design that has been utilized in many agricultural and industrial applications for years. Those years of use, or disuse, can take their toll ending in issues of fluctuation or surging, hot hard-starts, leaking and seal problems, or complete pump seize.
