A hole saw fit over the injector bosses, and they came out really easy.  A hammer and a sharp chisel got the fuel rail 
mount point out without much trouble.  Flipped it around, stuck the three pieces into position with some micro, with 
place the fuel rail in place to locate everything.  After that set, I smooth it all out with flox and three layers of 
8oz glass.

I still have a stubborn leak in my PSRU.  I think it may be around the rear seal.  I'm going to take a look at that, and 
I should be ready for more ground runs.
