Somewhere under the hood.
There is a vacuum check valve under the hood at the back of the engine. It is either broken or you have a bad vacuum hose.
NO. When a engine is running it makes it's own vacuum. That's why there is no vacuum hose on that year regulator. It is inside of the engine.
Your question is to vague to answer. If you connected a vacuum hose to a water hose you would be ingesting water into the engine.
The most typical cause of a vacuum leak is a cracked vacuum hose. The hoses get brittle with age, and cracks are common.
At the engine end of the top radiator hose.
Most likely cause could be the fuel pressure regulator located on injector rail with vacuum hose attached to it. This vacuum hose when disconnected after the engine has been shut off 15 minutes should show signs of fuel indicating a bad regulator.
It is at the engine end of the top radiator hose.
yes, it will be found on the side of the transmission where the vacuum hose attaches...possibly the passenger side.
If it looks like a mini UFO attached to a hose by the vacuum pump, it's called a vacuum diaphram.
The vacuum hose on the brake booster typically connects to the intake manifold of the engine. This connection allows the brake booster to utilize engine vacuum to assist in applying the brakes, making it easier to press the brake pedal. In some vehicles, the hose may also connect to a dedicated vacuum source or a vacuum pump, especially if the engine does not produce sufficient vacuum at idle. Ensure the hose is securely attached and free of leaks for optimal brake performance.
The vacuum hose should connect to the back of the intake manifold.
Front of the engine. Look for the engine end of the lower radiator hose.
