[Public-list] fuel tank in engine compartment

[Peter Hay]

  Roger:  I have a 12 gallon aluminum tank that fits under the cockpit just
ahead of the Edson steering pullies and above and behind the waterlift
muffler.  It is supported on a rectangular grid of angle iron (steel).  The
front cross member of the grid is anchored in the fiberglass.  A 1/2" of
plywood covers the grid and the tank is fastened to it with 3 3/16" bolts on
each side and 3 in the front (bolts thru the ply and the angle iron).   This
tank was installed when the replacement diesel was put in.  How they managed
to get it in there is anybody's guess.  I have taken the tank out and put it
back in with some stretching.  Incidentally platform is angled down toward
the engine.  The tank is 11" high in the front and about 7" in the back.
All access is through the access plate near the front of the cockpit sole.
Tank top is about 3" below sole.

  > After everyone's valuable feedback some tine ago, I have abandoned the
idea of a fuel tank under the cabin sole.  I am now thinking of moving my 11
gal. diesel tank to the area under the cockpit sole (so filler would be
accessed through the inspection port).  It was in the starboard cockpit
locker and took up allot of space.  I have a crazy scheme to run ventilation
air first through the seat lockers (from a cowl vent aft) then to the
forward end of the engine compartment and  aft.  If I locate the fuel tank
in the engine compartment, then all of the stinky stuff will be at the
downstream end of the ventilation flow.  Plus if the exhaust fan is at the
downstream end, everything will be under negative pressure which would help
prevent hot, smelly air from leaking into the cabin.

s under the tank and above the prop shaft.  It looks like everything will
fit and be reasonably accessible.  I seem to recall others mentioning their
tanks were located below the cockpit.  Any thoughts on how this might work,
particularly from a safety perspective?  I have learned that the flash point
of diesel fuel is 160 degrees F but don't know what kind of temperatures to
expect in the engine compartment.
