http://New to this, first time posting. I would like to thank this board a lot of outstanding information I used so far. I have a 68 Riviera that I owned from 1970. The last time I used it was 19 years ago when I started it up and put it in drive and almost went through my neighbors front window. No brakes. So 19 years later I was smart enough to changed all the brakes, spark plug wires, points and oil. I didn't know enough when I started it up to prime the oil. I thought it was in the oil pan. Wrong. I correct that by taking off the oil sensor and pumped oil through it. It works great after all these years.
But my question is I have a vacuum hose coming out of the firewall and I don't know where it should be connected. I can't find an item that is missing a hose. Attach Is a photo. It's right below the relay left hand side. Two vacuum line one is connected to a canister and the other one is the problem. Thank you
