Lines at the rack are 18mm. You can get them from underneath. Take the pass. side wheel off and get the lines off the pump itself. Unclip the single wire that is attached to the bottom of the reservoir. This is for the rear knock sensor and you DO NOT want to rip this wire. Bad day.
Once all of that is loose you can access the bolts through the pump pulley.
Pay attention to how the pressure line is routed before you remove it. It takes a funky bend somewhere near the exhaust. I just did this replacement on my brothers 01 GT and he pulled the line out before I could see it and it was a b*tch to figure back out. Return line should be easy.
If the rack is leaking it will be at the inner boots. Pull them back and check for fluid. And if you have a 2-wire connector coming from the rack where the steering shaft meets the rack on the drivers side and connects to something up on the trans then you have variable assist or "Magnasteer". Believe the RPO code is NV7 IIRC.
If you have to remove the rack here is the guide I used:
Jack and support car (usually at factory jacking locations right behind front wheels.
Remove both wheels
Remove the nuts holding the tie rods to knuckles and free tie rods from knuckles
Ensure steering wheel is straight and can not turn
Lift rubber boot on top of rack and unbolt the 11mm holding the telescoping shaft to the rack. Wiggle it free
Lower rear of subframe about 2-3 inches and support at that height using jackstands
Disconnect the two ps pump lines at the rack
Remove two bolts holding rack to subframe
Slide rack out the wheel well and reverse for installation.
Once completed, fill the power steering unit and start the car with it still in the air.
Turn wheel a few times in both directions an allow system to bleed air out.
Repeat with fluid/turning and sitting until system is at the correct level and not making noise.
