1965 Federal pump issue with a new Borgeson steering box Please Help

I have the exact same set up BUT no issues. Sounds silly but are your lines backwards? I had a hard time figuring out which of the two ports was pressure and what one was return. (Same sized)
My experience was excellent. Drives like a modern car over my Firm feel stage 2 box which was way better than factory. 66 Barracuda, Doug’s headers, 273/4 auto
