90 Supra - power steering leak

90 supra 7m-ge with about 170k miles on it (non-turbo rebuilt 50k ago)

i noticed a little red fluid leak, and I had just added a little steering fluid. I thought I had put too much fluid in the reservoir, and it had overflowed or dripped down the side.

then I started it, and the power steering started moaning. It wasn't doing this before, I had only noticed a very slight leak in the past, and now my reservoir was emptying out onto the ground.

i took off the engine under-cover to find where it was coming from.

it looks like the the steering rack boot had just busted or something. It was in two pieces and the fluid was coming out of it. I put my finger in there to see what was in there, and saw the shiny metal rod, and more fluid spilled out.

my main question is, can I simply replace this boot (or both, as they have boot kits for doing just this) and refill the steering fluid?

and I can't seem to find a clear answer to this question:
is there supposed to be fluid in this boot or no?

and if replacing the boot will not work, do I have to replace the whole steering gear?

my haynes manual doesn't cover the particular boot problem, tho it does show how to replace the rack and pinion steering gear.

thanks for any help
