Vacuum line coming from ball near canister?
Bought my first corvette a few weeks back. 85 automatic. It sat for a long time so I’ve been working on it, fuel system mainly. Anyways I’ve got a vaccum line that I don’t remember removing (actually looks broken) and I can’t find it’s home for some reason. It runs from the ball way up front drivers side, runs into a T, and then heads over or behind distributer to passenger side somewheres. Sorry for the amateur question it irritates me I can’t find it 😂. Thanks in advance for any help! PS tried to add photos but they won’t upload, maybe I need another help forum for that. |
i think I've got you covered. the vacuum line off the "ball" (which is actually an accumulator for the cruise control/HVAC systems) goes to a "tee" located somewhere around, and below your master cylinder. from the "tee" one line goes to the cruise control servo, and the vacuum line in question, routes behind the engine, along the firewall, and connects to a 2-way vacuum check valve off your the engine's plenum (RH side, and vacuum source). the other port of the check valve goes thru the firewall, and connects to your HVAC control panel. here's a shot of the 2-way vacuum check valve --
