Steve,

    I use a 0-30 psi fuel pressure sensor and gauge for my coolant pressure
sensor and its still working fine after close to 300 hours.  At one time
(and they may still do) UMA offered a coolant (or water) pressure gauge so
marked - they actually silk screened a new placard and placed it in the fuel
gauge I purchased from them.  So my fuel gauge actually says "Water
Pressure"

   The coolant gauge gives you pressure information that you soon begin to
correlate with your coolant temperature as well as OAT.  You soon begin to
notice when anything departs from the norm.  Its simple another bit of
information about your system which does nothing for you most of the time
but provide that comfort level that things are nominal - but, can alert you
to departures from the nominal which bear investigating.
