5.0 or 4.6 fuel reg on 4.0

Does anyone know if a fuel pressure reg from a 4.6 or maybe a 5.0 will bolt up to the 4.0 rail?

They all use the 2 bolt flange with an oring nipple, but just curious if any are the same mounting dimensions.

I really like how clean and simple these regs are...

But no one lists them for a silly 4.0 OHV of course.
