Even your return hose doesn't have to be anything special OEM genuine. I replaced mine with a hose cut to fit from autozone and shaped it with springs about 3 years ago and it still works fine

 

I used the GM Cold Climate P/S fluid that matches the specs that the D2 calls for. I added a little Lucas P/S conditioner as well. I just drained it out through the bleed plug, and filled the reservoir with new, not letting the reservoir drop below hale full. I did not replace the pump or hoses in my case.

Some dealerships have it, some may have to order it, or you can get it at Amazon.com or other online sites.
