I don't know the thread size but am intrigued why you want to know considering you will need both parts mated together in order for it to work.
If the pipe just had a thread on it I could understand you may want to find an adaptor to join it to, say, a braided hose with aeroquip type fittings.

In that case you will most likely need to make/buy a brass adaptor that can be soft soldered/silver soldered to the pipe on the rail or, better still, fit your adaptor to the compression fitting. Reason I would retain the compression fitting is that you want to keep the stub as short as possible as it makes removing the rocker cover easier.

Richard, did you ever adapt your rail for AN6 fittings?

yes, it is M12 x 1mm metric fine although i had to bore out the centre of the AN fitting to fit over the existing tube then chamfer the end slightly to accept the olive so the existing nut fit the new fitting, its all very snug and i used fuel resistant loctite on the tube and thread to create a good seal.
will be testing it this week for leaks.

sorry i missed this post, internal size is 9.525 so a fair bit bigger than standard which is nearer to 7mm, i have a 380 lph@43psi hp pump so given the likes of Mac and others who are running some pretty good numbers i think the system should cope well

Cheers; that's helpful - what did you do on the return side? I'm presently thinking a compression adaptor might be found to fit the bridge pipe if it's a common diameter

I've used standard fuel hose for the return into the regulator as I had 1/2 MM. to play with and needed to use a right angled fuel rail adaptor. The regulator the has a 1/8 npt to an-6 for the return to the swirlpot

180 degs fitting works well to put the hose along the top of the coil pack bracket and the back to the aem 380lph fuel pump
