Default LS1 Fuel Rail Adapter

Hey guys, anybody know where I can get my hands on an adapter for my LS1 fuel rail? Need a -4an female to 1/8" female npt (with 2 ports) to connect my fuel pressure gauge and nos cutout switch. I believe it's a -4an fitting on the rail, if somebody can confirm sizes that would be great. And if somebody has a source to get it, that would be awesome as well!

Thanks everybody!

Been looking and only thing I have seen so far is a blue anodized unit. Trying to find one in black if possible. Called Jegs and unfortunately they don't have what I want in stock at them moment.

Just went through the same thing installing an autometer pressure gauge sending unit, couldn't find it in black, only blue. Not by first choice, but it does the job... you would think these fittings would be more common than they are. Like finding a needle in a haystack!

Yeah I hear that. Will probably just use a brass tee fitting to run both the nos cutout and fp sending unit. Wish I could find that fitting in black. Tried Star, but didn't have what I wanted unfortunately.
