I'm sure I've seen someone on here fitting an ST170 manifold with the ford fuel rail to the zetec engine. I know the manifold end has a standard 14mm hole for the injector. What is the length of the injector and what is the size of the hole for it in the fuel rail, please?
I'm wondering wether to buy one and if the gsxr injectors will fit.

If anything, the Gixxer injectors will be a tiny bit too small - probably easily made up for with a thicker O Ring, though....but why not go with standard car injectors and the standard fuel rail? Make life much easier (my Vectra GSi purple injectors cost me a tenner)

Hi! I am fitting and ST170 engine into a Velocity and I am going to retain the original inlet system but wll be changing the fuel rail because this engine has a returnless fuel system setup and the ecu controls the pump pressure. There is no fuel pressure regulator on the injector rail.
