I bought a vapor separator from YO several years ago... same problem. You probably only have about 2 lbs. of fuel pressue right now.
The smaller fitting for the return is missing an internal restrictor. In other words... you got junk... return it if they let you.
From what I remember - the internal restrictor in that fitting / line is supposed to be about .040. but don't quote me.
