The pressure measurement of a perfect vacuum is 0 psi.
In a perfect vacuum, the pressure is zero psi.
The ideal pressure in a perfect vacuum is 0 psi.
The maximum vacuum pressure in psi that can be achieved by the vacuum pump is 29.92 psi.
The abbreviation for pressure is p
A typical vacuum cleaner generates around 8-12 psi (pounds per square inch) of suction pressure. However, the psi can vary depending on factors like the size and power of the vacuum cleaner.
In a perfect vacuum, the pressure is zero psi.

psi = pounds per square inch, a measure of pressure a vacuum is an absence of pressure.
Atmospheric pressure at sea level is 14.7 pounds per square inch.Psia(pounds per square inch absolute) is also 14.7 pounds per square inch.However psia starts with zero pounds per square inch at 29.92 in Hg which is a vacuum measurement (absolute vacuum) in inches of mercury or in Hg.14.7 psi atmospheric pressure is as high as atmosphere pressure will ever reach. all measurements below that is a vacuum. That is where psia come in. It can start measurements in a vacuum and continue with the same unit of measurement after it comes out of the vacuum at 14.7 psi.

Maybe and maybe not. PSIA makes it explicit that the measurement given is an "absolute" value; that is, its zero point is a complete vacuum. PSI may be absolute, or it may be given relative to ambient atmospheric pressure.
Psig (pound-force per square inch gauge) is a unit of pressure relative to atmospheric pressure at sea level. By contrast, psia measures pressure relative to a vacuum (such as that in space). Most pressure gauges, such as tire gauges, are calibrated to read zero at sea level, because most applications require the difference of pressure. At sea level, Earth's atmosphere actually exerts a pressure of 14.695948804 psi. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.695948804 psi. Thus a reading of 30 psig on a tire gauge, represents an absolute pressure of 44.695948804 psi.
A typical vacuum cleaner generates around 8-12 psi (pounds per square inch) of suction pressure. However, the psi can vary depending on factors like the size and power of the vacuum cleaner.
With vacuum line (from fuel pressure regulator) OFF and pinched , pressure should be between 47-54 psi. With vacuum line ON fuel pressure egulator, pressure should be between 38-46 psi.
