BIGFINDERMAN Posted February 24, 2014 Share Posted February 24, 2014 (edited) Got a few questions for you guys. I just got done rebuilding the throttle body on the pathy. Installed new orings and gaskets. Also replaced some old vacuum lines. My question is i found an open vacuum line with nothing hooked to it. It is behind the throttle body right beside the egr valve. With the motor running, i can fill it pullling a vacuum. This sensor, or whatever it is, also has a vacuum line coming off the top that runs to the bottom of the air filter base. See attached picture. I have no idea what it is called or what goes there. Also, there is a vacuum line hanging in that area that routes back to the passenger side firewall. I dont know where it is supposed to go either. See attached picture. Thanks in advance. Edited February 24, 2014 by BIGFINDERMAN Link to comment Share on other sites More sharing options...
ahardb0dy Posted February 24, 2014 Share Posted February 24, 2014 (edited) probably they go together, The line running along the firewall, does your truck have cruise? It may go to the cruise pump that is mounted in the pass. rear corner under the hood, Edited February 24, 2014 by ahardb0dy Link to comment Share on other sites More sharing options...
BIGFINDERMAN Posted February 24, 2014 Author Share Posted February 24, 2014 Yea it does have cruise. Didn't think about that. It appears to have not been hooked up for a while. Thanks for the info bud. 1 Link to comment Share on other sites More sharing options...
