93 chevy lumina high pressure hose placement

I'm replacing my high pressure hose on my
power steering on my 1993 Chevy Lumina
Euro 3.1 multi port. I've gotten the side of
the hose that is attached to my power
steering box unattached, however the lines
(both high pressure and low pressure run
side by side and go under the everything
and I have a skid plate made into the
frame) so I can not see which line is which
when they come out on the drivers side
and into the car. Is the high pressure hose
the one that is slightly lower and closer to
the fire wall where the hose goes into the
car or is it the one on top? I've tried looking
for specs but that's been uneventful. Any
help would be appreciated greatly.
