Power Steering Lines

[Chucktown Mako]

Question for you guys... I have a '96 Sierra with a 454. One of my power steering lines is leaking(the metal braided one). Problem is, where is connects to the pump, I cannot get anything on the fitting, due to where the other line comes in. There is no room to get a wrench on.

Do I have to pull the entire pump?

Anybody done this before?

Thanks in advance fellas!
