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.
The Vacuum line usually connects to the brake booster , or atleast it does in my Ford explorer
vacuum advance can connect anywhere there is vacuum present,carbuerator base is a good spot
It won't. That vacuum line tells the distributor When to advance the timing. There isn't enough vacuum loss to stall an engine.
When timing an engine, the vacuum line should be disconnected and plugged to prevent vacuum advance from affecting the timing reading. This allows for a more accurate static timing measurement. After setting the timing, the vacuum line can be reconnected.
the line is connected to the carburettor if you have one or to the intake manifold after the throttle valve. The purpose is to connect intake vacuum to the booster.
-Disconnect vacuum hose at old vacuum advance "can".-Remove distributor cap - wires can usually be left attached to cap, but red wire to cap may have to be disconnected to manipulate cap away from disty.-Remove ignition rotor.-Remove two ( usually ) screws attaching Vac. Advance can to distributor.-Carefully disengage vac. advance can lever from advance mechanism on disty.-Remove can.-Install new can;manipulate advance can lever ( rod ) into nub on advance ring before tightening screws holding down advance can onto distributor.-Install rotor.-Reinstall disty. cap - making sure 4 hold-down screws are seated securely.-Re-connect any wires disconnected from cap.-Re-connect vacuum line to advance can.Drive happily, with more power on hills.-J.Snick -- Question Authority --
That vacuum line connects to a nipple on the #3 carburetor just under the #3 intake. The other end connects to the vacuum advance mounted on the pulse generator at the rear of the engine. It should be routed under not over the fuel lines as they connect to the fuel pump.
On a Carter four-barrel carburetor, the vacuum advance typically hooks up to a ported vacuum source, which is usually located on the carburetor's throttle body. This port provides a signal that varies with engine speed and load, allowing for optimal ignition timing under different operating conditions. Ensure to connect the vacuum line to the correct port to achieve the desired performance and efficiency.
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.
To route the vacuum line on a 1976 Oldsmobile 88 carburetor, first locate the appropriate vacuum ports on the carburetor, typically found on the throttle body or intake manifold. Connect the vacuum line from the port to the desired accessory, such as the distributor advance or emissions control devices, ensuring that the line is securely attached and free of leaks. Be sure to check for any specific routing diagrams in the vehicle's service manual for precise connections. Finally, verify that all connections are tight and that there are no kinks in the line.
In a 1976 Jeep, the vacuum line typically connects to the intake manifold or carburetor to facilitate proper engine operation. It may also connect to various components such as the distributor vacuum advance, the climate control system, or other accessories that require vacuum pressure. For specific routing, it's best to consult the vehicle’s service manual, as configurations can vary based on the model and engine type.
It hooks to a vacuum port on the intake manifold behind the carb.
