Hot Rods power steering pump

I am using a power steering pump from a 72 mopar with a K-car power rack. This is the third rack that I blew the seals on. Can the pump pressure be changed on the mopar pump like they do with GM pumps with Mustang racks ? Or at least I thing that's my problem.
Thanks

 

KRC and Heidts make them.

 

Most steering pumps have a relief valve or hydrostat in them,they are adjustable but you would have to put a gauge in the line between the pump outlet and the rack,otherwise you wouldn't know where you are pressure wise. If you haven't got the gear or know what you are up to ,better off going to a power steering joint and get them to adjust it for you.But yes,they are adjustable.

If you want adjustability -
There's an inline regulator available too. Farting around with lines to use it is the next obstacle though.

 

How about using a K car pump? Should be correct pressure for the rack......
