If it is a point type distributor you will want to hook it to constant vacuum...somewhere on a port in the base plate. If it's HEI you'll want to hook it to one in the carb body. Something that has no vacuum at idle but pulls vacuum as you give it throttle.
There will be a vacuum hose that comes from the brake booster and hooks to the biggest port on the back of the carburetor. There is a vacuum hose that will come from the vacuum advance on the distributor and hook to the left small vacuum port on the front bottom of the carburetor. If you look at the front center of the carburetor at the bottom of it you will see a big vacuum port. The PCV valve hose will hook there and go in the top of a valve cover, should be driverside front. If it is a auto-matic transmission then there will be a long vacuum hose that is hooked to the modulator valve on the passenger side of the transmission and will go to a vacuum tee that you will see on the back of the intake manifold right behind the carburetor. Now I know there are other things on the engine that have to do with emissions but I long as you do not have to have it inspected you can disregaurd the rest of the stuff. The things that I told you about up above is all that you need to hook up to make this engine run good. All the other open vacuum ports can just be pluged off. I hope I've helped you. NEUTZ.
There should be a vacuum port on the back of the intake, behind the carburetor. It has to have vacuum on it at all times.
Need picture of carburetor vacuum connections and what they connect to
hook it up to the intake vacuum, normally the back of the carburetor where the brake booster may be plugged in. On a vehicle without power brakes, the vacuum port is normally plugged with a screw in plug.
hook a vacuum gauge up to any of the rubber hoses that are coming out of the intake manifold, such as the brake booster....
Your distributor needs vacuum to advance your timing during acceleration. That's why you hook up your line to the port that has no vacuum at idle. :O)
First you need a vacuum pump with proper vacuum hoses; then you need some container which you can seal air tight, hook the vacuum hoses to, and it must be strong and rigged as to not collapse when a vacuum is pulled. Container will preferrablely have place to look into it for expierment, or be made of glass. Now turn vacuum pump on for an hour or so and you will have an ok vacuum/empty space.
There should be a vacuum source on the carb above the throttle body that gives spark ported vacuum. You can connect a tube from this source to the distributor.
Depending on your carb, distributor and transmission, you have from zero to two vacuum hoses. If you have an Autostick transmission, there's a vacuum hose running from a port in the intake manifold to the control valve on the left side wall of the engine bay. (Hint: if you've got a car that came with Autostick and that someone's converted to manual transmission, the bracket for the control valve is the perfect place for your coil.) Most people don't have this transmission even if their car came with it--it's only a three-speed and it's hard to find parts for it, so most of those cars have been converted to manual transmission. The other hose you might have is for your distributor. The port is on the left side of the carb, and a hose runs between it and the metal vacuum advance can on the side of the distributor. If you have a 009 distributor or an aftermarket distributor like an MSD you don't have the vacuum advance can; if you have an aftermarket carb like a Weber you don't have the port. Therefore...you probably don't have any vacuum lines on your engine.
I'm trying to find out how to hook up the vacuum hoses to the carb in a 85 delta 88. I need to know how they go.
I just put a new transmission and have 3 hoses coming off the transfer case and need to know where to hook them to.
It does not hook to the intake. It fits on the big vacuum port on the back of the carburetor.
