Microphor compressor needed

[John Suter]

Hi Curt,

The mod requires a couple of check valves, "T's,"
and combination regulator/meters, a bit of
planning/thinking and you'll be in business. A common
modification diagram floating around, only adds engine
and 110V compressor air to toilet, and keeps the
existing 12V air as is, rather than create an "all for
all" system; therefore, I recommend first drawing your
layout on paper. Note the "plumbing location" of the
current microphor pressure regulator(s) as many have
been moved, some have two, etc. Last, don't overlook
air driven sewer-dump valves in the planning.

Doubt you'll have to physically move anything, but
if you do, consider re-locating the reserve air tank
moisture drain-line for more convenient access than
original. Add a master "on/off" switch close to the
12V compressor, if the original did not come with one,
and plumb/set the 12V compressor to be the compressor
of last resort (to preserve it). You already have the
ability to shut off the 110V compressor from the dash.
