There's a few tools that make the job easier, and a few that are required. You'll need a power steering pump puller and installer - AutoadvancePepO'ReillysZone will probably rent you one. I find it easiest to pull the pulley while the pump is still bolted onto the engine. The high pressure line comes next, this is the 18mm line that threads into the bottom of the pump. I use a 18mm crowsfoot line wrench to break it loose, since sometimes they're in there pretty good. Remove the supply line from the reservoir, the rubber hose with the spring clamp on it, then three 10mm bolts and you're home free. You'll need a new teflon seal to go on the high pressure line. Stretch it very carefully just enough to fit onto the end of the threaded nut, then spin it onto the nut as far as it'll go. Everything's a cake walk after that. The pulley installer you'll need will have an 8x1.25 thread.
