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. But one weak point on all automotive Stanadyne DB2 pumps that is often ignored by most rebuilders is the advance bore. The all-aluminum housing tends to wear out quickly where the steel advance piston is located. This causes excess return fuel and poor pump timing, which results in poor fuel mileage, excess smoke and low power. We address this problem by utilizing a steel sleeve in the advance bore. This gives us a more precise pump calibration and a superior injection pump that will last considerably longer.
