Diesel PMD tuning resistors fine-tune your fuel delivery.
If you are looking for increased performance, or if you accidentally lost or discarded the stock resistor when replacing your fuel pump mounted driver module.
These PMD tuning resistors are a good choice, no matter the reason- calibrate your injection fuel pump for average to high fuel delivery with these resistors.
Set of two resistors. Includes a number 5 (stock) resistor and the number 9 resistor for enhanced responsiveness.
Fits GM 6.5L Diesel models 1994-2000.
