I have a 1.8L EA series MPFI turbo model engine. It's out of an 87 gl-10 sedan four door. I am re-plumbing the thing after its been apart for years and need some help.

Next to the fuel pressure regulator there are three steel lines. One is high pressure fuel from the pump. The second is coming off the regulator and going back to the fuel tank as return. But the third... No idea... Any hunches on what needs to be connected to it?

I traced it to both the throttle body and thermomvalve. Other than that I am stumped.. http://images.thesamba.com/vw/gallery/pix/1196390.jpg

I hate to send traffic off site, but you are probably better off asking this at the USMB (ultimatesubaru.org) Those guys live and breath old skool, not many of those left around here.

Lol! It is a pretty old school question. Thanks for the recommendation buddy.

Thats the vent line connection. It connected the tank vent to the charcoal canister. I usually just delete the can and run a little filter on the line coming from the tank.
