Working on a vacuum leak on my '70 and i accidentally snapped a T. The thick hose coming from the left is coming from the vacuum tank. There is a T and a thick hose coming out of the right hand side that attaches to the wiper actuator relay. There other side of the T is a much smaller barb that was connected to a small hose that runs through the firewall. I tried to trace it but couldn't find where it's going. Since it's broken, while trouble shooting the vacuum issues i hooked the thicker yellow striped hose directly to the relay without the T and everything seems to be fine with the smaller hose disconnected. Any idea what that smaller hose is? Thanks

On my 73 (no wiper door). There is a similar T near that location which is for the climate control.

I think that is the vacuum source hose for your heater - defrost - vent control.

Thanks guys. That must be it! I'll have to check local parts store to see if I can get a new one..otherwise maybe jbweld

EBay is your friend... there are probably better options if you look but this should work.

I believe it also goes to you head light switch. Do your light pop up without the T connected?

You might be able to find what you need in the way of the T at Autozone or NAPA since they sell that sort of thing. I have no idea on a 70 where stuff goes, sorry.

Different hose... The headlight command vacuum tees out of the one way check valve.

Iceaxe is correct. Heater and vent controls and now a big vacuum leak with no heater or vent controls..

EBay is NOT your friend. They suck... lol

Here is a vacuum hose diagram for your car.

Head to your local autozone and get an assortment.

If you want higher quality replacement- just a few bucks more-

Go to your local hardware store and get some made out of brass- mine had all sorts of sizes a couple -three bucks apiece.

Good point by Richard454

The problem is that diagram has an error as it doesn't show the climate control vacuum tee the original poster was asking about.

I'll give you that... the page I posted was just for the headlamps... I didn't notice his issue was the broken T...

But carriljc is right, you can buy the same tee in the Dorman kit at most local parts houses. While it's white, you can paint it back to make it appear original. If the OP wants an original one he should email me direct @ Service@Willcoxcorvette.com, I've probably got an original one on a hose kit here... however, it would also be a 40 plus year old T and probably still be brittle like the one he broke.

Hello.

I'm reading your post and wondering if you solved your issue with the vacuum hose? I'm installing the Climate Control Vacuum Hose Kit (11492K Paragon) that I purchased form Corvette Central. The directions aren't very clear.

I'm replacing the long black hose that goes from the inside controller through the firewall.

Any help would be appreciated.
