Does anybody know if there is an adapter out there for the primary fuel rail inlet to eliminate the FPD without having to Tap a 1/8 NPT barb?

I've done this before on a previous car and although it worked fine it was many years ago and id prefer to use a different approach if there is one available.

Sard, Aerflow, turbosmart all seem to make adapters for the fuel rail but these are the 32.5mm hole centres and 11mm insert that only fits the end of secondary rail.

I think the primary rail adapter would need to be something like 36mm hole centres and 12mm insert.
