73 duster 318 power steering Issue

Hey guys. I need help figuring out a power steering issue.
i purchased a new borgeson power steering gear box and a new power steering pump.
Now when I go and try to add fluid and bleed the lines it builds up pressure and blows both the low pressure and the high pressure line.

Engine running I turn the wheels lock to lock. Fluid does go In and out, bubbles come out, then the belt starts to squeal, then, lines blow.

After about 8 times of blowing lines with fluid everywhere I threw the towel.

I tried with the engine off, fluid to the cold line, turned wheels lock to lock about 15 times.

Please help. Thanks.
Sincerely Tim Vogelsang
