What do you need to know about a vacuum line?
List of common Vacuum controlled Devices: 1. Exhaust Gas Re-circulatory Valve ( EGR ) 2. Brake Booster 3. Exhaust By-pass Valves ( like those found on Ferrari’s ) 4. Pop up Headlights 5. Cruise control 6. Crank Case/ Valve Cover Vent 7. Heating / A/C Vent Controls
How do you find a leak in a vacuum line?
Can Of Starter Fluid Using starter fluid is the oldest trick in the book for finding a vacuum leak. With the engine idling, take your can and spray down the vacuum lines and listen for the engine’s idle to change. When you hear the motor come off idle, and rev up slightly, you have got your leak.
Where is the highest vacuum in an engine?
Since the intake manifold represents the area behind the throttle plate, the highest vacuum that the motor produces will be found in the intake manifold. Because of this, the intake manifold will often have many vacuum outlet ports found on it. Vacuum Accumulator / Vacuum Box
Why are there so many vacuum lines coming off the intake manifold?
So why do I have so many vacuum lines coming off the intake manifold? Well, this is because that is where the vacuum is present. Since the intake manifold represents the area behind the throttle plate, the highest vacuum that the motor produces will be found in the intake manifold.

Where does the vacuum line go in a VW?
Let me make sure I have this straight: The MAIN vacuum line attaches to the port on the vacuum chamber at the rear (actually mine comes out of the side pointing toward the fuel pump, but that’s okay) and goes to the vacuum port on the left side of the carby under the stepped cam.
Where does a vacuum leak in a car take place?
Vacuum Leak Definition To start you off, we should answer the question; what is a vacuum leak? It is a situation where there is a leakage in the vacuum system, mostly on the relay pipes. It will, most of the time, take place between the engine and the mass airflow sensor.
Where are the vacuum lines on an S-10?
The older S-10s had the vacuum lines from the dash to the engine. Those would crack easily. The line was routed along the driver’s side and entered under the brake booster if I remember correctly.
How do you replace a vacuum supply tube?
To refit the tube, you simply push the vacuum supply tube back into place. If too much pressure is applied and the intake air duct tube or its connectors are damaged, replace the entire hose; the red connectors are not sold separately. Remember, these hoses need to be disconnected if you are removing the intake air duct. They are important.

Where does the Elek VAC Reg in the diagram go?
The “Elek Vac Reg” in the picture is actually called the EGR vacuum control solenoid and it’s ‘diagnostic’ switch. the hose that looks like it goes nowhere should actually be attached to the smaller pipe that runs along the firewall with the ‘old, pre-recall’ PCV fresh air pipe to the sir cleaner. This hose was left intact after the recall.
Where is the third vacuum line plugged in?
The other port that is plugged. If you have a 2003 or newer the third port is adjacent to the second port and its right next to the throttle position sensor,…sorry no pics…..your on your own, but since you read those two links at the very top, it provided you with more than enough info, you should completely understand!
When do you know you have a leak in your vacuum line?
With the engine idling, take your can and spray down the vacuum lines and listen for the engine’s idle to change. When you hear the motor come off idle, and rev up slightly, you have got your leak.

Where does the vacuum come from in an engine?
Also, the more efficient the pump, the more power it makes. A motor is constantly moving air in and out of itself. The Vacuum that a motor produces comes from the intake strokeof the motor where the crankshaftdraws down the pistonand air is pulled or “sucked” into the motor.
