Product Description
FASS RK02 REPLACEMENT SYSTEM RELOCATION KIT FOR 1998.5–2002 DODGE RAM WITH 5.9L CUMMINS
The FASS RK02 relocates your DRP02 (Dodge Direct Replacement Pump) toward the fuel tank on 1998.5–2002 5.9L Cummins trucks. Shortening the suction distance lets the pump push under pressure instead of pulling under vacuum, improving priming, reducing aeration, and extending pump life.

FAQ
Why relocate the DRP02 toward the tank?Lift pumps perform best pushing under pressure. Shorter suction distance improves priming and reduces cavitation for better reliability.
Does RK02 fit 2003–2004 5.9L trucks?
No. Use the RK04 kit for 2003–2004 applications.
What parts are included?
New mounting brackets, wiring harness, and hose specific to the relocation. See the install manual for component callouts.
Do I need a suction tube or sump?
Not required for the relocation itself, but many owners add the STK1002 to improve fuel supply on higher-demand setups.
