The black hose from the control goes through the firewall to where? I assume this is the source but dont see a connetion point.
does anyone have a good diagram of the hose routing,

Re: 71 heater control vacuum hoses
Vincent check under the right passenger hood latch there should be a "T" connection for the vacuum for the heater. The connection is 1 small hose and 2 larger hoses the larger hose goes to the wiper door relay in the Right fender.

Re: 71 heater control vacuum hoses
I'm not seeing it Paul, all the hoses are new and accounted for, could I have missed cutting a "T" in.
recap
we are talking about a small solid black hose that comes from the heater control in console, through the firewall in its own gromet just above the gas peddle and I believe is the source of the vacuum. nothing I have shows me the source connection. frustratating.Comment

Re: 71 heater control vacuum hoses
Vincent I should have asked first what engine do you have and also do you have A/C. I am going off memory for my 71 LT-1 and other 71 cars I have had my hand into. A/C cars may have this hose at your location I do not recall again memory it should then "T" in to your white vacuum supply hose. That goes across to your wiper relay right fender.
More help move to the bottom of this page there are additional threads that may relate to your subject go to the first one by Joseph Mule open the thread and move down to post #36 the numbers are on the right side of the post open Terry's 3rd photo and you will see the "T" connection just to the right of the relay on his 1970 LT-1. Hope this helps

Re: 71 heater control vacuum hoses
it is a 71 LT1 car of coarse no A/C. so there should be a T in the white stripped hose? the vacuum hose diagram I have dosen't show this.Comment

Re: 71 heater control vacuum hoses
All 71 non A/C cars this is the place that I remember where the "T" is located look at Terry's photo that is what the connection looks like except it is under the right hood latch area.

Re: 71 heater control vacuum hoses
Vincent move all the way to the bottom of this page there is a list of additional post that may relate to our discussion. The first one by Joseph Mule go to reply #36 the 3rd photo is the one I looked at of Terry's car.
They moved the connection over there in 71 due to the steel line that goes across the fire wall (bad term) from close to the storage tank 3/4 the way across to the pass side.

Re: 71 heater control vacuum hoses
I see the photo and the T in the large yellow vacuum line connecting the small line. 71-72 do not have this T. the yellow hose from the wiper relay connects to a hard metal pipe across the firewall to the driverside and connects to the T in the green stripped hoses.
can anyone else help with this?Comment

Re: 71 heater control vacuum hoses
I am posting two , maybe useless pictures of my 71 BB car.
On my car the only thing coming out on its own grommet by the throttle cable is the tach drive cable. Is what you are looking for near that? If I have some reference I may get better shots for you.
What I have is a tee on the pass side with the small vac hose entering the cockpit behind the distributor.

Re: 71 heater control vacuum hoses
Ken, the pic of the T is blurry but I think that my be the connection for the heater vacuum. Is that T cut into the yellow wiper relay hose?Comment

Re: 71 heater control vacuum hoses
Vincent,
Yes, it connects to the yellow stripe hose that goes to the Vacuum relay valve located on the inner fender by the washer reservoir.
I have better pics this time, see below. I should have added arrows. In the first pic it is the small hose behind the washer cover at 1 o'clock. In the second pic you can see the yellow hose with a small one below it turning to the distributor.

Re: 71 heater control vacuum hoses
Thats the "T" connection I'm missing. with a new vacuum hose kit it dose not show this, or in any other book or diagram I have. In my car this hose enters the cock pit just above the gas petal with its own gromet. the hole behind the distributor has a rubber plug in it. strange. thank you.Comment

Re: 71 heater control vacuum hoses
Vincent that is the "T" that I was telling you about in Ken's photos. Like I stated this connection was moved when the metal lines were used in 71 production 70 production had the connection shown in Terry's photo I also believe the same spring clamp was used in 70 or 71. As Ken has stated the small hose would enter the fire wall at approximately behind the distributor.
