I got the vaccum tube blues.

Ok let me start by putting this schematic up.

Ok Right next to the thing labeled fuel tanks on the schematic is a circle that sais A/CL DV. That the Air cleaner diverter. I need to get that thing workin. The schematic shows it going to the A/CL CWM (Have no idea what CWM is, but im pretty sure its that thing with two vaccum nozzles on my air cleaner thats busted). From there the line goes to the V REST (AC Only, which i do have AC) I have no idea what a vaccum rest is or what it looks like. Its not one of those black plastic bubble things is it? Because I don't have one. Then we go to the A/CL BI MET which eludes me completely I have no idea. From there it goes to MAN VAC, which im guessing is a constant vaccum source.

Ok bear with me vaccum lines are a whole new science for me, ive never had a vehicle old enough to have more than just one or two. Alright how critical is that A/CL CWM? Should Get a new one or just skip it? and try to find these other components. This is also my first carburator.

My electric choke doesn't seem to be hooked to anything either. Thats pretty sweet isn't it. I need a carburators for dummies book. I just looked up it needs to be hooked to a keyed 12 volt line.

The carb sias motorcraft on it. I have an Edelbrock performer 289 intake manifold that was just sitting in the bronco when i bought it does anyone use one of these? The eldelbrock website sais it will fit my 302, and it looks brand spankin new. Can I get past some of this vaccum nonsense with a new edelbrock carb and this manifold?

Theres probably more but thats all ive figured out today. That and My motor seems to leak from everywhere, Gotta clean that up and look again after a drive. But it looks like mostly front seal and oil pan. So thats not too bad.

Well that is a whole bunch of questions bundles up in that post . OK, first off not having a full factory vacuum system hooked up may get you in trouble with the emissions inspector. If that is not a problem in your state, then there is a whole lot of possibilities. Not all vacuum functions are there for emissions, like the CWM, A/CL DV, etc. There are some bare minimums, some desirable additional functions (if in a cold area), and some that do emissions control.

What is it that you want to accomplish?

Yes,

The Edelbrock Performer has two versions, one that supports heat control valves and one that doesn't. If you look at your stock intake, from the front, there is a vacuum device on the right side next to the carb. That is the Heat control valve, (a nice function in the winter if it works . It is coupled with a heat control valve on the exhaust manifold on the same side of the engine. (By the way I said looking at it from the front which reverses the normal reference labels as that is actually the left side of the truck when you are setting inside B) .

Bare minimum would be the vacuum line to the distributor, vacuum line to the automatic transmission, vacuum line to the brake booster, and vacuum line to the heat controls (requires a vacuum reservoir). After that I would add heat control formerly called a heat riser), The carbon canister purge lines and control (an emissions function but also it keeps your gas tank pressure equalized), and those mysterious (CWM, A/CL DV things :huh: ). Oh yah, a VREST is a restrictor that controls the speed at which the vacuum changes to a particular function. These things aren't as hard to understand as some people think. If you look at the vacuum diagram, each major function is color coded ant the vacuum tubes match, with the exception of black, (it gets used for multiple things).

Good luck,

Here is wahat I am currently running

Thank you very much,

Im just trying to get some bearings on this and make sure im barking up the right tree. Sorry for rambling on, I tend to do that.

No problem, I gave you the wrong side of the manifold for the Intake Heat Control Valve. On a 302 it is on the passenger side. Also, the stock Ford carbs usually don't use a 12V connection for the electric choke but aftermarket carbs do. On the stock carbs it is usually hooked to the stator of the alternator which is some where around 7V. A 12V connection will burn up the element.

Good luck,
