FAQ
Will the DRP02 improve VP44 life?
Yes. Stable inlet pressure and reduced aeration help protect the VP44 from low-pressure damage and cavitation.
Do I need the RK02 relocation kit?
Highly recommended. Relocating the pump rearward shortens the suction side so the pump pushes under pressure instead of pulling under vacuum, which improves priming and longevity.
What if my truck has an in-tank pump retrofit?
Add a FASS STK1002 suction tube to ensure reliable supply to the DRP02.
Is wiring included?
Core wiring is included for factory-location installs. For higher current capacity and clean add-ons, use the FASS WH-1006-3R relay harness.
