It was definately missing. I checked all the packaging and the white tubing that came with this unit.
I just got back from J&L and there is now a 100gpd in the black line leaving the RO membrane.
I'll report back once I do some more math.
And once again, Thanks hillegom, you may have solved another issue for me

Down the road I'll change over to the inline style when I go with a 75GPD membrane. I've heard the 75s are more efficient.
