Fuel pressure regulator plumbing?

Just got the dart running and went out for a drive. My fuel pressure is way to low, like 2.5 Lbs. Not sure if my regulator is bad or if I have it plumbed wrong?
I have the regulator adjusted all the way up. (Screw turned all the way in per instructions.) And it's still not over 3 psi?

Pump is summit eletric and new.

Bottom -8 line is fuel in.
Left side -6 is fuel to the Y block.
Right side -6 is return line.

I thought both sides labeled our
would be regulated but it seems like it's just pumping right back into the tank?

The regulator is a cheep Holley one.

Did I screw up the plumbing or should I get another regulator?

Thanks.
