Fuel Rail Thread Sizes

I am putting on an AFPR and have all the lines setup, I need 2 adapters to replace the dampener and the stock regulator, but cannot find out what the sizes are for those two inputs.

Does anyone know what size thread they are? I can bring the rail to a hardware store and find the right size, but I'm hoping someone knows off the top of their head.

Thanks

Well, first off, it's metric of course, and I see no metric to AN fittings on that site at all.
Find someone who sells Aeroquip fittings, and you will find what you need.

Talk to Driftmotion, they carry what you need. Look up their fuel dampener bypass. I have this, along with their Aeromotive FPR kit, -8 fuel rail fittings (bought my fuel rail separately, although they carry -8 fuel rails), and all the other stuff that's needed.

12 MM X 1.25 is the thread size for the FPR. I have the other size written down in the garage. I will find it when I go out there.

Also most go with -6an for the fuel system, not -4an

EDIT: The dampener is 14M X 1.5
