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.

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.

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
