I got a rebuilt steering box to replace one that was leaking. Trying to reuse the lines, but the pressure line port on the box seems too shallow and I can’t get the threads started.
Looking at the old unit, it seems like the flange with the o ring sits lower into the box and on the new box the port is not deep enough.
I there something I should do to get it down? Turn the box, put more pressure on it, new lines, or just take it back?
First picture is the old box, second is the new one
