Paul, in the attached drawing, the part of the injector that the

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.

Jerry,
Although I'm well behind you in building my demonstrator, I did run
into the
'Injector man' at my local Mazda shop and he was very helpful. He
supplies
new /second-hand ( cleaned and tested) for the huge range of
modifications
done to all types of engines.

His advice to me was identify ( guesstimate) what the HP requirements
and he
will match that with the GMC/Ford/ or other equivalent as they are
much more
cost effective ( half the price).

Once you have done that and have an injector, you can match the
injector
boss. In my case 1 ( each inlet tube) injector might do the job
(140hp),
with yours 2 ( each tube) will be required

Given this information, I think we have been working back the front
with the
injector selections, by trying to identify injectors rather than
nailing the
HP first. These Hp numbers are fairly general 200, 250 etc. Given
your rig,
I'm guessing your looking at 200hp ?

George (down under)

I think around 220 hp.  So far no one  has warned me off the Mazda
injectors for the power we expect.   Jerry
