Nice clean design!
 
However, I am a bit curious about the fuel connection the two secondary injectors - looks like it would have to be a "hose" type fuel feed or a custom fuel rail design to accommodate those angles.
 


That was my thought, exactly.  But then I noticed the screw holes on each side of the injectors.  Is there an attachment adapter that isn't shown?
 
=============
Thanks for the kudos Ed =)
Yes the secondary injectors have retainers and floating caps on top into which Swagelock T's are installed so that hard stainless lines are daisy chained through. Once I figure out how to attach a picture I will take one and do so. This portion of the manifold is now complete to the silicone couplers and now needs joining to the rest of the fuel system via the primary fuel rail block.
 
This is where we ask a few questions:
1. are pulse dampers still used on the input to the primary fuel rail?
2. what is the best pressure regulator available?
3. we have seen diagrams where the fuel goes to a T then separately to the primaries and secondaries then back together at another T to enter the regulator. We are not leaning this way due to concerns about vapor lock; T'ing the lines reduces flow through each branch by 50%.
