GM 1994-2002 6.5L Calibration Resistor for Pump Mounted Driver (PMD)
Calibration Resistor for Pump Mounted Driver (PMD) for 1994-2002 Chevrolet & GMC 6.5L This Calibration Resistor provides the final fuel delivery information and is needed if you plan on leaving the old PMD on the pump and replacing it with a new one mounted elsewhere. It is highly recommended that the resistor be changed when a new PMD is installed. If your PMD is installed without a resistor it will not operate properly. To figure out which resistor you need simply look for the number etched into your current resistor. If you do not have a resistor currently we suggest using the #9 resistor.
