Paul,  I think  you were going to send me an Auto Cad drawing of
the
fuel rail.   I can use that when you get the time.  Thanks,  Jerry

OK will send by private email as even the zip file is too big to
publish.

Paul Lamar

Don't do more drawings.   I can easily get the dimensions   from
what
you have already sent.  Thanks,  Jerry

I knew you would figure it out :) Dimensions on drawings are for
people
without computers and NC tools. Now a days a 3D like that is fed into
a program that generates
a NC machine tool program with out any one ever actually looking at
the dimensions until
the part comes out the other end :) It was Monty that convinced me of
that a couple of
years ago.

It is a good thing too as for some strange reason dimensions don't
come across
well in either ACAD dwg, iges, or dxf. IMHO it has to do with the
dimension fonts different
drawings like Rhino ACAD Solid Works etc. etc. choose as standards.

On the other hand if you are making a part by hand  you need a
drawing
with dimensions in front of you.

Paul Lamar

I am thinking of having the fuel rails made in a local machine shop.
They will definitely need measured drawings.   Jerry

Let me know if loading it into ACAD and using the ACAD dimensioning
facility
does not work. In any event you need to make a prototype to check the
fit.

Do you have a Mazda fuel rail pressure regulator? If so loan it to the
machine shop so they can match the threads.

Have you decided on what you are going to use for fuel plumbing?
I recommend 3/8 minimum.  AN -6

Paul Lamar

Yes,  AN 6. We don't have enough demand for this fuel rail to justify
CNC.  Right now,  I  just need one.   Jerry

If you make it longer and don't drill out the ends for taping and don't
drill the injector holes it will work for a wide range of installations
including my own.  Just drill the long 3/8 inch hole down the length.
Consider me having ordered one for this installation. 11" long
ought to be plenty for a two rotor. Have your guy make two.
Bill Scherts, do you have your fuel rail already?

Paul Lamar

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.

KIS Cruiser # 4045

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.
