Hey guys, I bought a truck that was in pieces when I bought it. Got it up and running but I can't seem to make sense of these two lines on the passenger side fender well.

The one comes right off the air box. The other is bundled with the group that goes to the throttle body.

Any help would be much appreciated.

Thanks

 

Any thoughts?

 

Mine has a big filter on the that fender with vacuum lines hooked to it. I believe it's some kind of emissions charcoal filter.

 

I'm on mobile right now but from the pics it looks like your truck is pre-92. My 91 had vacuum lines running to the air filter for a valve that opened to let heat from the exhaust manifold warm up the air goin into the motor.
