K.B.D.P. #5 & #9 Calibration Resistor – For 6.5L PMD FSD
Brand: K.B.D.P.
A simple, effective way to restore fuel calibration on 6.5L PMD systems.
The K.B.D.P. calibration resistor set is designed for the PMD (Pump Mounted Driver) on 1994-2002 6.5L turbo diesel engines in Chevrolet and GMC trucks like the C/K2500, 3500, Tahoe, and Suburban. These resistors, numbered #5 and #9, are OEM-style components originally used by GM to regulate peak fuel flow on DB4 electronic injection pumps. They are built as high-quality doorman resistors for a precise fit within the PMD assembly.
Installation is straightforward: you slide the resistor onto the female PMD plug terminals. If you need to remove it, a paper clip or snap ring pliers can help. This set is a direct replacement for the factory calibration resistors, helping to maintain proper fuel delivery and engine timing in your 6.5L diesel powertrain without the need for a full pump replacement.
- OEM-style design
- Easy to install

Buyer’s Guide: What to Consider
Choosing the right injection pump for your 6.5 turbo diesel involves matching engine specs, part numbers, and pump type. Here are five key factors to consider.
- Engine Compatibility: Ensure the pump matches your engine model, year, and part number. Many pumps are specific to certain engines like the 6.5L or Cummins 5.0L.
- Part Number Verification: Always compare the pump's part number with your original. Using the wrong number can lead to poor fit or performance issues.
- Pump Type: Decide between a high-pressure CP4 pump, a VE rotary pump, or a calibration resistor. Each serves a different fuel system design.
- Voltage and Pressure: Check if your system requires 12V or 24V and the correct pressure range. Mismatched voltage can damage the pump or engine.
- Installation Requirements: Some pumps are direct replacements, while others need adapting. Consider your mechanical skill and available tools before purchasing.
Conclusion
Selecting the correct injection pump for your 6.5 turbo diesel depends on your specific engine and vehicle model. Whether you need a calibration resistor for a 1994-2002 Chevy or a high-pressure pump for a Nissan Titan XD, verifying part numbers is essential.
For most 6.5L diesel owners, the K.B.D.P. calibration resistor set offers a simple fix for fuel flow regulation. If you need a full pump replacement, ensure compatibility with your engine’s make and model for the best results.
