Just picked up a 94 Sierra 1 owner yesterday and on my way home I got a pinhole in high pressure power steering hose. Picked up a new one today and was going to put it on. 2 questions. On the pump side, the "insert" that the fitting screws into...does anyone knowhat size that is? When I tried taking that fitting off, the whole thing spun. Also, what size wrench do I need for the steering gear side of the high pressure line.
