Paul, in the attached drawing, the part of the injector that the clamp
fastens to is  longer than my "stock" Mazda injectors.  Is the one you
drew also a Mazda injector?  Further, what injector  do   you
recommend
  for my application?     If I build the clamp as shown,  it will be
taped for fuel line hook up similar to what Klaus did (no hard fuel
rail).  I assume I  need a regulator before the return to the tank
These injectors will be aimed right into the bell mouths, but how far
from the bell mouths should they be?  There is also the issue of
nailing down the clamp inside the box.   Clearly I  need help with the
final design.   Jerry

p.s. can you recommend a text on fuel injection?

The injector in your picture has something around the feed barb.
Perhaps
it is a seal of some sort. Mine do not have that part and the barb
is 5/8th of an inch long. Try removing it. I also remove the plastic
on the injection end as well. Here is a picture of an injector when
that stuff removed.

Paul,  can you design the clamp so that it holds the injectors
vertically?  That will cut down on stuff blocking the bell mouth.   I
would like the clamp rotated 180 degrees so that I can drill and tap
the base to screw the clamp down to the plenum floor.    Thanks,  Jerry

Something like this?
