1994-2002 GM 6.5L Diesel #9 Black PMD Calibration Resistor

Description 1994-2002 GM 6.5L Diesel #9 Black PMD Resistor for Stanadyne 6.5L DS Electronic Diesel Fuel Injection Pumps Flight Systems part number 508900-9 is a fuel calibration resistor located in the PMD wire connector cavity of Stanadyne electronic DS model injection pumps that were used on 1994-2002 Chevrolet and GMC trucks with the 6.5L diesel engine. The injection pump fuel delivery is fine-tuned with a resistor in the PMD. The resistors range in number from one to nine. This number nine resistor will deliver the highest fuel delivery. If no resistor is used, the pump will default to the number five. We recommend using the number nine resistor to give you that little extra performance.  A check engine light may come on if no resistor is used. Note:  Stanadyne changed the connector between the wiring harness and the PMD when they updated their PMD to the gray-color version.  Use this resistor with the black style Stanadyne or Flight Systems black colored PMD’s. This resistor can be used with the gray Stanadyne PMD if you snip off the pointy ends and make the short ends flat.  Install with the number showing.
