Fuel rail thread size question!

[3.0 GT]

I am installing a new external fuel pressure regulator and already have all the hoses needed. But I cant seem to figure out what size thread and pattern the fuel rail return hole is! The joiner i have that i thought would fit is an 12MMX1.5 METRIC MALE but the threads were to wide.

Can any one who knows please help me out with the right thread size I need for where the stock fuel pressure regulator goes?

The middle and front holes are M12x1.25, and the rear one is M14x1.5

So you need a M12x1.25 to -6AN adapter. I like Summit, due to the easy searching for fittings. www.summitracing.com

Edit: This should work nicely: http://www.summitracing.com/parts/EAR-949091ERL/

1.25

Edit got beat.

And double on summit. I get all my fittings and hoses through them. There awesome and shipping is super quick. Tho sometimes there boxes are too big.

I ordered 2 1/2npt plugs They sent it in a massive box. lol.

Most threads on our cars are 1.25 except for some of the larger bolts.
