Here's some of the parts.

-----------------------------------------------------------------------------------

#1. Begin with safely supporting the front end of the car. I used jack stands instead of ramps, so the wheels were free to turn.

#2. To prevent pump and rack contamination, thoroughly clean the banjo bolt (rack output) and pump input connections with brake cleaner.
Overall system:

There's a banjo bolt under all that gunk, trust me:
