Anybody know what size they are or where I can get them? Theyre the little fittings I need to signal lines?



Im guessing from the Japenese instructions, thats its 1/8 PT but I just want to make sure...



Also, is there a difference between NPT and PT?

I think the PT sizing is not tapered like the NPT. It should be 1/8th npt as the wastegate line. I got all my line at summit racing.com. I made them out of -4 AN fittings....pretty important for it not to come off.
