When I talked to FiTech they told me that the supposed "advertised" vent on the Command center "is a RETURN" and "NOT" a vent. Said there was an advertising mess-up on calling it a vent. This was why some are having fuel puking out their vent.

So I asked if the 440 & hemi cars 1/4" return line would be big enough to handle the return from the Command center. Don't remember his exact quote but it was a negative.
