I have found this large open vacuum line underneath the brake booster. It's not pulling any vacuum, but it leads back to the vapor canister.


I have also have a capped off port on the intake mani, under the brake booster line.

Should this be connected to the intake manifold to pull vacuum from?

 

I was looking in the haynes manual and couldnt find it, but i'll check the 01 service manual after dinner and see if i can find it.

 

well I think that open hose should connect to manifold vacuum, and I there's a diagram in the emissions section which also displays that ..... BUTTTTT..... the vacuum diagram on my truck doesn't show that connection. I dunno.

 

Mine has the capped fitting on the manifold too, I think it's just for something optional... And would that open line maybe be a vent hose or something? I know it doesn't go on that fitting. Not sure if mine has that, I'll check tomorrow

 

Well I had a look at mine today and got some pics.... That big hose is indeed a vent for the canister, on mine it's got the vent cap on the end, and comes up on the passenger side wheelwell right beside the vent line for the CAD

 

i really appreciate those pictures man. My tube of coming up on the drivers side, right below the brake booster.

 

NP dude, I was out tinkerin yesterday and thought I'd get some pics of these things people have been asking about...

Is your canister on the drivers side too? Mine is on the passenger side, right about under the rear door or so... I just always assumed that the big vent hose was for the tranny or transfer case, I've never followed it all the way back before... So I learned somethin anyway

 

any update Maxx as to the location of this vacuum tube?

 

what do ya wanna know? I thought this was solved, that tube just being a vent hose? I can go out and have a look again if ya want but that's how it is on mine

 

Well the pictures you posted were from something on the passenger side, and my vent hose comes from the drivers side and goes to a canister. I want to know if your driver side hose goes anywhere?
