Since Mid January I have unsuccessfully tried to obtain a diagram of the interconnection of vacuum lines between the carburettor and intake manifold on a Suzuki Swift with a G13BA engine (March 1995) I have been informed this engine has a throttle body I sent a photograph of the engine showing a carburettor and no injectors, to date I have received no reply.If you have no information on the vacuum line set up for this engine with a carburettor Please inform me. I will then seek information elsewhere Thanks for your previous sssist

One runs to the charcoal canister, and the other goes to a port running to a metal tube connected to the intake manifold (I'm not familiar with the Edge, but on the mid-90s Taurus, the intake manifold tube connects near the throttle body, and the connection to the charcoal canister is a fitting near the bottom of the radiator). There should be a decal on the top of the radiator frame showing a diagram of the vacuum hose connections.

Without more detail it is hard to say which diagram you need but if you copy and paste this into google.com's search field then select the word images directly underneath where you pasted it, you will see many options.

Copy and paste this;

Or, I have added a link here that has a view of the top of the motor with vacuum lines marked.

vacuum lines on intake manifold Ford F150 Forum Community of Ford Truck...

I found lots of info for you, hope it helps, you will probably like the last one the best:

Yeah, about ten times better. Look, you need vacuum in the intake manifold, you have to have it or air wouldn't rush in from the air cleaner, the engine would not breathe, and it would sit there and barely run, or not run at all.
By design, vacuum is created when the piston in a cylinder is pulled down by the crankshaft and the intake valve is open. So air from the intake moves into the cylinder, leaving a vacuum (lower air pressure) in the intake manifold. For more air to be drawn in, but it's a set amount of air. Vacuum leaks and leaking intake manifold gaskets pull in extra air and lean out the air/fuel mixture too much. So plug off that hole and make sure no vacuum leaks.
For your '72, an inexpensive vacuum gauge would be a wise investment. Check this site for its usefulness:

All engines run with a vacuum in the intake, a good engine should have a steady vacuum of between17 and 21 inches on the gauge at idle. The tighter and less worn the engine is, the vacuum will be higher, like 21 inches Hg. But should be at least 16 or 17, and steady. Learn how to use a vacuum gauge and you can tell a lot about the engine's condition-just check the site.

Big breather from valve cover to air cleaner, the small vac line runs from there to the FPR.



These next are standing in front of the car:

Intake manifold lower outer runs to EZL

Intake manifold lower inner (right side) goes to switchover vac valve on driver fender. The other side of this vac valve goes to the throttle body

Intake manifold lower inner (left side) goes to switchover vac valves on passenger side fender. These then go back to the EGR valve once making a loop under the distributor cap for whatever reason.

Intake manifold rear runs to a 'three' way valve (or 'Y' connector) on the secondary firewall. This is usually a vac leak.

Sorry I don't have the diagram, but I do have a diagram of the engine and component locations. Your vacuum system is fairly simple. You have a MAP sensor attached to the air cleaner. I have pasted a picture below. It has one electrical connector and one vacuum hose that goes to the intake manifold or the throttle body.
Behind the right headlight is your evap canister. This will have a hose or line running to the fuel tank. Then it will have another hose going to the purge valve. The purge valve should be close by and it has a connector plus another hose that goes to the intake manifold.
Then you have the PCV hose that goes from the PCV valve in the valve cover to the air cleaner or intake manifold. I think yours just has a hose from the air cleaner and the rest is internal.
There is one more vacuum hose, and that is the bog one that goes from the intake manifold (or throttle body--looks to me like there are a couple of vacuum ports on the back side of the throttle body, and there may be a "T" on one of the hoses) to the brake booster. It this one was off, the engine would not run, as the vacuum draw is large. Please let me know if you cannot figure it out from these instructions and provide a picture, if you can.

Hello, I have the 1993 Ford Festiva shop manual in front of me. The vacuum hose on the Fuel Pressure Regulator goes to the intake manifold. The manual says that the fuel pressure is maintained at a constant 36.3 psi, and when the engine vacuum drops (caused by high fuel demand) it causes the fuel pressure to increase inside the regulator. There should be a vacuum diagram on the bottom side of the hood that will help to show you what vacuum port on the manifold that it attaches to. If the decal is gone, look on the intake manifold for a vacuum port that is open and causing a vacuum leak. I hope this helps.

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.

if only one vacuum line then? the vacuum line goes from the vacuum advance on the side of the dizzy, to the carburettor, just around the throttle linkage if i recall. hope this helps.

hmmmm... im not expert in these kind of problem but... try to replace the diagram? it is possible?
