=0AI built a plane with = a steel tube frame, so I had a lot of pieces of tube with different dimeter= s and wall thicknesses.  It was trivial to find a size that the inject= ors would squeeze into.  Then I used a washer instead of a cutting whe= el in my tube cutter to add a shoulder.  It is what I'm using as the r= eceptacle in my manifold.  I'm using the stock fuel rails, but it woul= d have been a simple matter to weld the sockets onto a 3/8" tube to make a = rail.
