Description
Overview
The FASS RK04 Direct Replacement System Relocation Kit is purpose-built for 2003-2004 Dodge Cummins trucks and SUVs equipped with the 24 Valve engine. This kit is designed specifically to work with your FASS DRP Series Direct Replacement System, allowing it to be repositioned further back on the frame rail, closer to the fuel tank. Instead of forcing your fuel pump to pull fuel from the tank under vacuum, the RK04 relocation kit sets up your DRP System to push fuel under pressure to the Cummins engine, which is the way these systems are engineered to perform best.
Vacuum-side failures are one of the most common reasons factory and replacement fuel systems wear out prematurely on the 2003-2004 Cummins platform. By shortening the distance between the fuel pump and the tank, the RK04 kit reduces the workload placed on the pump during the draw cycle and lets it operate in a pressurized state instead. That shift from pulling to pushing fuel is the core benefit of this relocation kit and the primary reason FASS engineered it for the DRP Series lineup.
What’s Included
The RK04 is sold as a complete kit and includes the wiring harness and hose needed to relocate your DRP System. Everything is matched to the stock application layout of the 2003-2004 Cummins truck/SUV chassis, making it straightforward to integrate with your existing DRP Series setup.
Key Benefits
- Relocates the FASS DRP Direct Replacement System closer to the fuel tank
- Converts fuel delivery from a vacuum pull to a pressurized push, reducing strain on the pump
- Addresses the leading cause of premature fuel system failure on this platform
- Includes wiring harness and hose for a complete relocation setup
- Engineered specifically for the DRP Series on 24 Valve Cummins applications
Fitment
The RK04 relocation kit is designed for 2003-2004 Dodge Cummins trucks and SUVs running the 24 Valve engine, matching the stock application configuration (AAIA ID: FKRH). It’s intended to be used alongside your FASS DRP Series Direct Replacement System to achieve proper relocation and pressurized fuel delivery.
If you’re running a DRP Series system on your 2003-2004 Cummins and want to give it the best possible working conditions, the RK04 relocation kit provides the hardware needed to move the pump to a position where it operates the way it was designed to — under pressure, not vacuum — helping it hold up over the long haul.
