Default Fuel Rail dimensions

I am building a fuel rail from an extruded aluminum blank and was wondering if anyone knows the exact distance between injectors. I was hoping to avoid tearing into the fuel system until all the holes are drilled. Thanks.

From memory, I am almost 100% sure that the injectors are spaced 91mm apart (1.8).

Without measuring, it's probably the same as the bore spacing, which is.....?

a great question. Anyone have a 1.8 fuel rail laying around that they could measure the distance from one edge of a bore to the same edge of the next bore? That would do it. And no... I'm not being lazy. I'm being efficient.

Now that I'm at work and remembered that I Faro'ed the '99 era BP head, the spacing between each injectors is 91mm. ftjandra was correct. I doubt the '94-'97 head was different.
