Seriously off-topic. :-)

If you're putting in tubing, you need to make sure that all of it
flows better than the original lines.

The other concern is one of the steering getting the required
pressure soon enough if the pump is modulated in some way. The
steering input may "get ahead" of the pump's modulation making a
slalom-type exercise an adventure.

Then dump the power steering. :-)
