Just a quick thought, one of my ex-girlfriends had a '95 dodge intrepid
which was "tri-fuel" ready, and whenever i'd have to go get parts for it
they always asked if it was the tri-fuel or regular model.  I never checked
the trunk, but i do remember a fourth line coming to the fuel rail, perhaps
this was for LPG?  I know a lot of the ford police vehicles here stateside
are now offering LPG offerings, as our city has a few.  Just a thought, i'm
sure you can all find a '93-97 dodge intrepid in a local junkyard with the
3.3liter multi-fuel engine in it.
