I need to find out how the vacuum lines need to run with this new setup. Can anyone help me? Bob | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy Callmebob, actually the vacuum wiper lines can be removed entirely and their source of vacuum at the intake manifold can be capped or plugged, hope that helps. | | | | | Joined: Feb 2014 Posts: 17 New Guy | | New Guy Joined: Feb 2014 Posts: 17 | My truck will not idle if I plug the manifold port. | | | | | Joined: Oct 2006 Posts: 1,847 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 1,847 | well you have a problem, because that is how it is done. Did you have a vacuum leak somewhere and have the carb adjusted to compensate? | | | | | Joined: Feb 2014 Posts: 17 New Guy | | New Guy Joined: Feb 2014 Posts: 17 | That could be possible because the vac wipers didn't work. Thanks I'll check it out today. | | |
