On my 1978 Camaro one vacuum line goes to the EGR valve and the other goes to the carbuerator.
Ported vacuum - part time.
yes at the carb
It depends on the year of the car.....but if you are running HEI ignition (74 and later) it will run to the carb. It goes to a ported vacuum signal. You will find a ported vacuum on a fitting that is above the carb base plate. It should have no vacuum when the engine is idling but will have vacuum when you rev the engine.
NO. It needs ported vacuum. This means that it should only have vacuum on it when you bring the rpms up off of adle.
The brake booster runs to the large port in the rear of the carb or you can tap into one of the intake runners. You may have to T off some vacuum lines as the 600 carb probably won't have enough to run everything. There are fittings that will screw into the large rear port of the carb that have 2, 3, or 4 smaller Ts for running all this. Manifold vacuum will be any port on the carb base plate and intake manifold. You'll need manifold vacuum to the plastic reserve vacuum ball....that's for the HVAC controls. The intake should have a couple of places to install switches into the coolant flow. You will need the ported EGR vacuum switch for your 84 truck. The switch should have two places to hook vacuum up....one you will hook up to manifold vacuum and the other runs to the EGR. There should also be a ported switch to operate the canister purge valve. If your distributor runs a vacuum advance, run that to a ported vacuum port.....anywhere above the base plate of the carb. That should get you started.....as I'm just going by memory.
where is the ported vacumm switch located on a 4.o lt for a96 ford explorer xlt 4wd 4dr
On a Dodge truck, the vacuum switch is on the transfer case.On a Dodge truck, the vacuum switch is on the transfer case.
Depends on the vehicle and how it is set up. Some are connected before the throttle plate (ported vacuum or delayed vacuum) and some are connected after the throttle plate (straight manifold vacuum). More info needed.
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.
If you mean specifically, what type of vacuum, the answer is manifold vacuum. Manifold vacuum is constant and doesn't, change with throttle valve opening, the way ported vacuum does.
No it should not, It is now hooked to direct vacuum witch is wrong. It should be hooked to ported vacuum. That means that it only has vacuum when you speed the engine up and not when it is idleing.
