Paul, I do not have it yet, but I do know that the injector plugs
have to face to the sides in order to fit. No clearance for them
to be on top, and they won't fit facing down. This means you
cannot do it as a "T" machined part as shown in the transparent
fuel rail.

That is on our KIS cruisers of course that have a very limited over

head.

OK Bill thanks for the heads up.
I'll have to face the center two inwards towards the side and
the outer two towards the outside and machine some of the T away.
Do you think that will work? I'll do a 3D of what I am babbling
about. I can still start with what Jerry is making. This is not
precisely the needed spacing but it is just to illustrate what I
am talking about. the space been the two center injectors on the
KIS is about four inches.

I haven't read all of my email yet, so if this is no longer germane,
feel free to discard it.

If the injectors would fit when the connectors are pointed up, but
cowl
clearance problems prevent orienting them that way, then could one not
simply change the plenum box from rectangular cross section to
trapezoidal cross section?  That would change the injectors from being
horizontally mounted to slightly upward, which would make the
connectors
be closer to horizontal.

That is a good idea Russell but in Bill's case it is too late.

Bill Schertz certainly does not need any help from me, but I am going
to make up some fuel rails per the article I referenced  the other day.
  Any length, any space between injectors,  will not matter.   These
will have a 3/4 fuel  square fuel rail.  AN-6 both ends.   Probably
about one month before I get around to it.  In the case of Paul's
manifold, we will need a way to bolt the fuel rail so that it snugs the
injector into the socket.    Jerry
