My FPR located on primary fuel rail, huge question

I have a j-spec tII motor in my 10thAE, and the pulsation dampener and the pressure regulator are swapped around. PD on the upper secondary rail, FPR on the primary. I have a universal FPR im installing and need to replace the old regulator with a banjo bolt.

I haven't found anyone else with this sort of setup OR links to pictures that might help me, so my question is would the threading on my FPR be the same as everyone elses?? Which i believe to be M12x1.25 correct? My engine is apart and need to get any parts ordered very soon, thanks fellas.

Just try it and see if it works?
I would think it should work out that way...
I don't see Mazda carrying different part numbers cause of different thread sizes.

Got some pictures. The threading on the secondary rail where the FPR should go looks much larger...

More specific, please. Both of the banjo bolts on my s4 rails are a larger thread size than the one i need (I.E. the banjo bolts on the opposing side of the PD and the FPR).

Which one would i need
