The Sandens will run in any position; I turn them ninety degrees and
run the fittings out the sides using one of the custom fittings with
charge ports from Classic in Tampa Fl.  They make several different
angle fittings and I always make sure the valve cover can be removed by
doing a mock up of the hoses/fittings before smushing the ends on.
With Hawks and the adapter plate you need the extra clearance; the "U"
shaped hose ends and top mount will sometimes hit the hood. I also use
a condesnsor fan with a control unit that is adjustable; comes on
automatically with the AC and an be adjusted to come on at a specific
temperature.  The one I have been getting has a built in diode to
prevent the fan from pushing juice the wrong way in the system and also
has provisions for using two fans if you really need that or two small
fans  instead of one big one.  Condensor fans here in Fl. are almost a
must have..
