Fuel Coolant Pump Relocation Kit: The Smart Upgrade for Your 2020-2026 GM 6.6L Duramax L5P

If you own a 2020-2026 GM 6.6L Duramax L5P and want to install a larger, more effective oil filter, a fuel coolant pump relocation kit is the essential solution. This kit moves the factory fuel coolant pump away from the oil filter housing, creating the clearance needed to run the oversized PPE Deep Engine Oil Filter (P/N 114000750). This single upgrade provides superior 5-micron filtration, more than double the filter media area, and increased oil capacity, leading to better engine protection and long-term reliability . In short, the relocation kit is a straightforward, bolt-on modification that unlocks a significant improvement in your truck's oil filtration system without requiring any permanent modifications to your vehicle.

Why You Need a Fuel Coolant Pump Relocation Kit

The factory configuration on the 2020-2026 GM 6.6L Duramax L5P places the fuel coolant pump very close to the oil filter housing. This tight clearance makes it impossible to install a larger, more efficient oil filter, such as the PPE Deep Engine Oil Filter (114000750). The relocation kit replaces the factory heater coolant pump mounting bracket and moves the pump further away from the oil filter, allowing you to use the larger filter .

The benefits of using the larger PPE oil filter include:

  • Enhanced Filtration: The PPE filter provides 5-micron filtration, which is significantly finer than the standard filter. This means it traps more contaminants, keeping your engine oil cleaner for longer .
  • Increased Oil Capacity: The larger filter holds more oil, which helps maintain oil temperature and provides a greater reserve of clean oil for the engine .
  • Greater Contaminant-Holding Ability: With more filter media, the PPE filter can hold more debris before becoming clogged, extending its service life and maintaining consistent oil flow .

What the Kit Includes and How It Works

The PPE Fuel Coolant Pump Relocation Kit (part number 114002700) is designed as a complete, easy-to-install solution. It typically includes:

  • A fabricated bracket that replaces the factory mounting bracket .
  • Molded hoses that connect the relocated pump to the factory coolant lines .
  • Hose clamps to secure the connections .
  • An electrical harness extension cable to reach the relocated pump .

The installation process is straightforward and can be completed in about an hour, even in a driveway . The basic steps involve:

  1. Draining the coolant system.
  2. Removing the factory fuel coolant pump from its original mount.
  3. Installing the new bracket in the designated location on the frame rail.
  4. Mounting the pump onto the new bracket using the provided hardware.
  5. Connecting the molded hoses and securing them with the clamps.
  6. Extending the electrical wiring using the harness extension.
  7. Refilling the coolant system and checking for leaks.

As one reviewer noted, "The relocation of the bracket... the only thing you need to do is add a bolt to the kit," but overall it is a "very easy installation" . Another user recommended using the OEM hose clamps instead of the ones provided in the kit for a cleaner installation .

Compatibility and Vehicle Fitment

This kit is specifically designed for the 2020-2026 GM 6.6L Duramax L5P diesel engine. It is compatible with the following vehicles :

  • Chevrolet: Silverado 2500HD and 3500HD (2020-2026)
  • GMC: Sierra 2500HD and 3500HD (2020-2026)

It is important to note that the kit is designed to work in conjunction with the PPE Deep Engine Oil Filter (P/N 114000750). You cannot use the oversized filter without this relocation kit due to the clearance issue .

Common Installation Tips and User Feedback

Users who have installed this kit report high satisfaction, with an overall rating of 4.74 out of 5 stars from 19 reviews . Some common feedback and tips include:

  • Easy Installation: Most users describe the installation as "simple," "easy," and a "no brainer simple upgrade" .
  • Quality Materials: The bracket and hoses are made from high-quality materials, ensuring a durable and reliable fit .
  • Wiring Harness: Some users noted that the electrical harness extension could be improved. One reviewer suggested using nylon cable ties to create a "lock" on the connector to ensure a secure fit .
  • Hose Clamps: A few users recommended using the original OEM hose clamps instead of the supplied gear clamps, which were described as "made out of recycled bottle caps" . This is a simple substitution that can improve the overall quality of the installation.

The Importance of a Reliable Fuel Pump

While the fuel coolant pump relocation kit solves a specific clearance issue, it is also a good reminder of the critical role your vehicle's fuel pump plays. A failing fuel pump can cause serious engine problems, including sputtering, loss of power, hard starting, and even stalling . For a high-performance diesel engine like the Duramax L5P, a reliable fuel pump is essential for delivering the correct fuel pressure and flow to the injectors.
