| Post subject: | Need help w/vacuum system...Please |
72 Dart Swinger 225ci automatic/air God bless this forum! I was thrilled to find it. Trying to finish a 2 year restore and don't have any vacuum behind the dash, thus none of my linkages controlling my heat, defroster, etc. are working. I can manually control the linkages and all air is blowing in the right places. I have vacuum to the distributor, carb, etc, and the engine is running great. My shop manual doesn't provide a diagram of this system. Where can I find one? Any ideas are greatly appreciated. Thanks......Gary |

Sounds like the vacuum hose isn't hooked up to the vacuum tap on the #6 runner. There should be a little plastic hose with a rubber nipple on it on the firewall, close to the wiper motor. This should be hooked up to the vacuum tee on the #6 intake runner. This little hoise supplies vacuum to the underdash heater and a/c doors. Or your control head might be bad. Reed |

| Post subject: | Is this the line? (pic) |
www.angelfire.com/falcon/gwp36530/vacuumline.jpg Is this the line you mean? If so, I am confused because it is actually 2 lines coming thru the firewall. Pictured, you can also see the vacuum connection plugged off on what I think you are calling the #6 runner (intake?). Is this the right lines? Thanks alot.....Gary |

That thing plugged off on the intake manifold is the vacuum tap. Those rubber hoses might be what I am talking about. Where do they go? If they don't go anywhere right now try hooking them up and see what happens. I would guess that one powers the underdash A/C stuff and the other actuates the water shutoff valve when the a/c is turned on. Whats that one hose in the picture that stops right above the intake manifold? Reed |

Reed, That line is coming from what looks to be some type of vacuum cannister. There is another cannister on the passenger side of the radiator which has 3-4 lines going to it. I plan to pick up some fittings today to start connecting some lines to see what happens under the dash. I'll post results. Thanks much......Gary |

The cannister on the passenger side of the radiator with three hoses going into it is the charcoal cannister. This does not affect the A/C system. The line which supplies vacuum to the A/C doors should be rather small, about 1/4 inch inner diameter tops. The other cannister may be part of the EGR valve vacuum amplifier system. Reed[/code] |
