Pump-Mounted Driver (PMD) Relocation Kits

The pump-mounted driver (PMD) (a.k.a. diesel injector pump drver) is an electronic switch that controls the fuel solenoid on the injection pump.

The Problem: On Stanadyne DS4 electronic fuel injection pumps used on all 1994-2002 6.5L GM trucks and vans, the OE pump-mounted driver (PMD) module is mounted directly to the fuel injection pump. This location creates two problems. The first is inefficiency. If a PMD module attached to a fuel injection pump needs to be serviced or replaced, you need to reach the fuel injection pump, which is an extremely time-consuming, labor-intensive repair. The second problem is that the location on the fuel injection pump subjects the PMD to excessive heat, a known cause of this high failure part.  

Our Response: Our PMD Relocation Kits provide a solution to both problems. If you install the kit upfront when installing the fuel injection pump, you’ll save significant time when diagnosing and replacing the PMD module in the future. As for the heat-related failure, our remote-mount PMD Kit allows you to relocate the PMD, which will help improve service life because of increased airflow around the module, thereby keeping it cooler. Here's what's included in the kit:

  • New pump-mounted driver
  • Relocation harness
  • Aluminum heat sink
  • Mounting hardware
  • #9 resistor

Already have a functioning PMD? Our S39002 PMD Relocation Kit provides only the components.

In addition to PMD Relocation Kits, we offer PMD Resistors separately: the #5 Resistor, which matches the stock settings, and the upgraded #9 Resistor, which promotes high performance settings and increased fuel flow. Both resistors are engineered to fine-tune fuel delivery to your preference
