Evo injectors are 560's and it should be very easy to find a set locally (Scheides just replaced his, I'm pulling mine out soon, and Zac is replacing his soon too). Also, for the Evo IX fuel pump, Zac (hellomynameis) has his for sale right now so just check the classifieds.

Rather than doing all that nonsense with your 16G pieces and stock 14B just buy a brand new 16G so you can bolt it right in with zero complications or issues. You will thank me in the end.
