bought a Nisei UICP off another member, he accidently gave me the wrong couplings( gave me an intake one!) anyhow, no big deal. I have the upper one that connects to the compressor outlet pipe, but not the lower one. anybody know off hand the dimensions of it? I ordered a straight 2.5 in coupling guessing thats what it would be but im just trying to get confirmation on this incase i have to order another size. thanks in advance for anyone who can shed some light on this for me.

 

i reused the stock one. i have a nisei one piece.
