I did modify the original primary fuel rail by cutting off the ends and welding AN bungs in their place. But that limits me to using the 550cc injectors.

So, I checked and discovered that the the standard injector will fit under my custom intake using a stock 13B fuel rail. I don't see how I could adapt the factory "low-profile" fuel rail to accept standard 460cc injectors. I'll have to take a picture of what I'm talking about when I get home from work. The "low-profile" injector that fits into the primary intake port sockets is fed through a screened opening on the side of the injector. It has o-rings on the body to seal when inserted into the fuel rail. I don't see how you could modify this to accept a standard injector. Also, there are two mounting brackets just next to the injector sockets that holds the fuel rail and injectors in place. I concluded that the easiest solution would be to use two standard 13B primary fuel rails, connecting them in the middle with a tube, than build one from scratch. If push comes to shove I can build one from scratch. A picture will make this much clearer. Stay tuned.

You lost me.  I did modify the original primary fuel rail by cutting off the ends and welding AN bungs in their place.  But that limits me to using the 550cc injectors.  I feel these are way too big for a n/a engine.  My objective here is to go to a 460cc injector.  But they don't come in the "low-profile" style (correct me if I'm wrong).  So, I checked and discovered that the the standard injector will fit under my custom intake using a stock 13B fuel rail.  I don't see how I could adapt the factory "low-profile" fuel rail to accept standard 460cc injectors.  I'll have to take a picture of what I'm talking about when I get home from work.  The "low-profile" injector that fits into the primary intake port sockets is fed through a screened opening on the side of the injector.  It has o-rings on the body to seal when inserted into the fuel rail.  I don't see how you could modify this to accept a standard injector.  Also, there are two mounting brackets just next to the injector sockets that holds the fuel rail and injectors in place.  I concluded that the easiest solution would be to use two standard 13B primary fuel rails, connecting them in the middle with a tube, than build one from scratch.  If push comes to shove I can build one from scratch.  A picture will make this much clearer.  Stay tuned.

Thanks,

Mark, my Cosmo 13B has the same injectors as 20B. I cut both ends of the original steel fuel rail and tapped them for 1/4 NPT thread. I m talking about the injectors mounted on the engine block. Can you do that with yours if you have it?
