    well a while ago i picked up two systems..one out of a mid 70's truck(with a 350) and system out of an 80s truck(with a 454)

    (i have a 75 blazer)
    then i started to put one of them in my truck. but now the high pressure and low pressure lines to the system seem to be switched in position. one now fits the left hole and the other now fits the hole on the right. i have to cross my original lines inorder to make them fit. I dont know if this is right, i havent read anywhere that the lines are crossed..sorry hard to explain...both systems are same with hole size positions..

    i'll try to take pictures of what i'm talking about...but right now easter bunny is calling.

    You mean on the steering box, or on the booster?

    ok heres what i'm talking about the left line fits the hole on the right and the right fits the left hole.
    i just dont know which line is which and what can go where. if i need to bend new lines thats fine or i can probably just bend these.

    Yeah, they are reversed on some hydroboost systems... just bend the lines so they will bolt up to the port they fit in.

    BTW: those are your front and rear brake lines, not high and low pressure.

    Um, the front brakes are nearly always are plumbed to the port closest to the firewall. I'd get the right tube nuts on the right tubes and re-doubleflare the tubes.
