Hey guys, I am gonna order an aftermarket elbow pretty soon and I have a very quick question would like to know before I make the purchase.


Below is a picture of a SR engine and I was wondering what is the blue circled part for?
I noticed most of the elbow doesn't have the hole to allow the pipe from this thing to plug in, what should I do about it if I get an aftermarket elbow?

Do I have to mod it to make it fit, or just let it unhook?

Thank you very much!



Sorry for using JMI picture for reference, hope you don't mind. Please do let me know if you wish me to remove it.
