Ford 6.0L Regulated Return Fuel Line Kit
This RR kit is unlike any other kit out there. Gone are the days of having fuel lines snake all over the engine bay and get in the way of when you need to do actual work on your truck. Our kit is out of the way and allows for turbo, up-pipe, down-pipe, etc removal/installation without needing to open the fuel system and exposing it to corrosion producing air. The RR kit will help your truck to hold fuel pressure with larger injectors as well as run quieter due to allowing for an alternate path for entrained air in the fuel to go instead of through the injector nozzles wearing the injectors out prematurely.
NOTE: We do recommend the use of our up-pipes with this kit but it is not required.
