I've just blocked the heater outlet with a rubber plug at
   present
                    for initial starts but was wondering the same thing.
                    I think others have pulled the tube from the block and
                    tapped and plugged the hole.


          Why not use this for cabin heat?????

     I was originally going to put a heater core in the cabin and feed the
     water as per Mazda's design.
     I've now planned  to install a standard airbox from Vans with a feed
     from heated air post radiator, like Dave Leonard' in the photo. Can
     Dave L comment?
     In the end weight and simplicity seamed to win for me.

   Guys, I think what is circled in that pic is a fuel pressure
   regulator, but
   I could be wrong...or maybe that pic was just referenced.

   Your right Rick. It got interchanged with the one steve sent. Both
   pictures are the same.

The photo of Dave Leonard’s was to show the heater box and scat hose.
