By expanding them, you create a vacuum inside them; given a portal (your mouth, nose), the vacuum will pull the ambient air in, just as a vacuum cleaner pulls things inside by creating a vacuum.
To test for leakage in the system.
Sterilant
Between 28 to 30..........
Pull em off and put in new ones.
pull the hose off the vacuum advance and some of them have a set screw inside the hole.
A gas engine does not have a vacuum pump. Vacuum pumps are used on diesels only as they do not pull vacuum from the manifold. Gas engines use vacuum lines (usually stemming from intake or throttle body)
The things that pull things in without touching are called suctions.

This is due to a higher amperage draw from the vacuum. Where a lamp most likely pulls less than 1/2 amps. The vacuum pulls more as it runs. Therefore the load, or amps, make it harder to break the circuit which causes the sparks
Gasoline will eventually boil under extreme vacuum at any temperature but the problem is trying to pull enough vacuum. During a recent experiment it took about 8 hours to pull enough vacuum to boil it to vacuum, the gasoline was at 72 degrees Fahrenheit. Temperature does play a small role when trying to boil under vacuum, this would be true if just trying to boil under normal atmospheric pressures. We pulled enough vacuum to double what was even in space not an efficient way to vaporize fuel.
Clarification: I am wanting to know how much vacuum I need to pull to get water to boil at 150 degrees.
