Whats it called?
On the p/s near the dist, I have these three vacume lines. One goes to the ORB of power and the other to the manifold. The three vacume lines are connected some kinda vacume "T" or vacume round looking thing (wish I had a camera). Its broke. Where can I get a new one and whats it called, or does someone have a part number for it? Thanks for any help.

if it looks like this, it is called a heater control valve. the part number is 14101545(dealer). the auto electric group has it also. same part number.

Nope thats not it. Its real small, round and has three vacume hoses coming off of it. Like control valve or something. One vacume hose goes to the ORB of power.

No, its smaller and round. It has a vacume line coming out and going to upper manifold (305TPI) and a hard plastic vacume line, not sure were its going and then a smaller vacume line going to the orb of power. Its not more that 2 inches in length and round.

I think you mean the check valve thing. On mine, it's about halfway between the map sensor and the coil. One line goes to a port on the plenum next to the map sensor, the other 2 go wherever. It's kinda funnel shaped and at the fat end, the part closest to the firewall on mine it has 2 hose ports. one straight out the back, the other aimed at a 90 degree angle from that one. The 3rd goes straight out the "front", smaller tip of the valve and goes into the plenum. I hope that's it at least. As for where to get it or the part number, I'd like to know that as well, lol.
