Need help with this

[mini612]

Hi guys, I'm swapping an M30b34 into an E30. I've looked and searched the web and forum and cannot find information on this.

What is this nipple on the fuel rail and where does this connect to? I know about the fuel in and fuel out, but what is this and where does it go?


Thanks.

No one on here know where this goes? It's not the intake or the return nipple, and yes I know where the intake and the return nipple is. I just can't figure this one nipple out.

Do I even need it?
