I believe it's a -6AN the fitting you need is sold by Autometer.
Sorry I don't know the p/n but it's also a single piece fitting -6 female AN on 1 end and 1/8 pipe female on the other end. :cheers:

It is a -6 and we keep most of this stuff in stock.

If you can't source the fittings and adapters locally please give me a call.

Thanks,

Shawn

Edited:

It is not a -6AN

I have an extra rail here, it is a -4AN not a -6AN.

I was almost 100% sure, but had to check for myself.
