Re: Taurus RACK & PINION??????
First, confirm whether it's actually the rack that's leaking or the high pressure hose. If it's really the rack, the "book" time for a replacement is 4.5 hours including alignment. Rebuilt racks come in two varieties, short and long. The short rack does NOT come with inner tie rods. The long rack does come with inner tie rods. Neither come with outer tie rods.
As for a DIY, it kinda depends your skill level and shop equipment. You will need to put the vehicle in the air and lower the rear engine cradle. That means extra jacks and jack stands. It's also pretty tight working quarters to disconnect the old lines and the steering coupling. Air impact tools help a lot.
The easiest (but a little more costly way) to do this job is to forget about wrestling with the old P.S. lines. Just cut them off and replace with new ones. Pop the outer tie rods (you'll need a tie rod puller for this). Then center the tires and wheels and lock the steering wheel. (if you don't, you'll screw up the clockspring on the airbag). Then disconnect the steering coupler, remove the rack bolts, lower the rear engine cradle and slide the whole assembly out the side. Reverse to install and then get it aligned.
