Flight Systems #9 Black PMD Resistor for GM 6.5 Injection Pumps

FS 508900-9 / Stanadyne 308900

Calibration Resistor

The injection pump fuel delivery is fine tuned with a resistor in the PMD. The resistors range in number from one to nine. The number nine 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.  Use this resistor with the old style Stanadyne or Flight Systems black colored PMD's.
