I should've named the thread missing vacuum line but oh well. cant find the line that hooked up here, any help appreciated!!




This is the line i have plugged off because i cant find where it went before.





Heres where that line goes from the t going towards the passenger side, to another t, both going into firewall




and heres where it goes towards the intake manifold, t goes into the manifold and other line goes to cruise control i believe, it runs up past the throttle cable.

 

The line looks collapsed... is your truck a 4x4? Does it work?

 

Yes 4x4. No It dosent work. But its not a line. Its a plug. Made so it wasnt sucking air. Theres a line that connects to it I just cant find for the life of me. Wanna say a 90 degree corner went off it

 

Its marine grade shrink wrap haha

 

Wonder if a line broke, and that was the 'fix'...... It does get pretty warm in there, the shrink wrap probably just did its job.

Is there a white line around there somewhere, should come up from the vacuum switch on the t-case. (there is a green one as well, but, that one is SUPPOSED to dead end, its just a vent line.)

 

In this pic of a diff truck I found on here doing the plenum you can kinda see the line I think but im still lost on where she goes and what she does.

 

And I have a full repair manual here. But it dosent show anything usefull for vacuum lines

 

Should be a vacuum diagram on a sticker under the hood, probably on the radiator support. (emissions label) I don't think it shows the lines for the 4x4 though.....

 

Ive looked at that also. Never helped.. ill check my 4x4 tomorrow and give a update

 

Well 4x4 issue is just the actuator and all the lines are where they are suppose to be. So still no answers on where this line is.
