Wish I would have known about the 5.5L/UAT option before I ordered :/ The 6.5L is WAY to much fuel, and the diameter is too big to fit through the former that is factory installed in the CARF Rebel Pro.
I'm hoping I'll be able to trim the former, and not too much, to make it fit, and I am going to mark where 5.5L is and only fill it to there.
