Vacuum line help

[Roont]

Where does this one go. I traced it with purple to show it comes from along firewall. I dont know where to plug it in. Fuel pressure regulator? Where is it?

Also this port on airbox tube by throttle body.

if I had to guess without looking at my car that line should be under the intake and go to the port on the inlet hose.

That's the vacuum line that runs to the fuel pressure regulator (as the regulator forms part of the fuel filter on the later model M62's). You can see it here, part number 13;

You can just ghetto fix it with a dual male barbed fitting, or if you want to go OEM, get a new full line piece like this;

Thank your lucky stars the fitting isn't snapped off on your inlet tube! That happens so often. But even if that does happen, you can just get a threaded male brass barb, drill it out a bit and put that on instead. Everything is fixable. Good luck

Sorry guys. The previous owner or maybe mechanic had this line running along the driver side upper wheel well for some reason!! I didn't realize the long long rubber hose connecting it to the intake for some reason when taking it apart hahaha

What a pain in the butt.

$50 for a tube like that...should be a felony!
