A lot.
No, it means it is running. It may or may not be pumping gasoline with the proper pressure. Fuel pressure test will verify if it is working properly.
From your description I would guess that your car has a bad fuel pressure regulator. To check the fuel pressure regulator remove the vacuum connector from the throttle body. If gasoline comes out of a vacuum line the diaphragm has ruptured allowing excess gasoline to enter the intake through the vacuum line. If that is the case you will need to replace the fuel pressure regulator.
oil and gasoline can flow through pipes.
The tank comes with a residual air pressure of about 40 PSI. This can be regulated through the air nipple at top of tank. If you are going to use 30/50 as is common, then set tank air to 28 by adding or letting air out of this nipple while the tank is empty of water. After setting this pressure, adjust the pressure switch to come ON at 2 psi above this , ie 30 PSI. Now when the water level lowers in the bladder the pump will switch ON before the tank is empty. If tank residual pressure is very low on an old tank it is possible that your bladder has holes.
This is called siphoning. The gasoline-filled tube, when the end that is not in the gas tank is lowered to a point below the tank, it creates a pressure differential inside the tube. Just as liquid pours from a glass when it is tilted, so does the gasoline flow through the tube. As long as the tube in the tank is below the level of gasoline in the tank, the gasoline will continue to flow until the flow is interrupted (or until the tank is empty).
yes it is because it keeps the cost down through eligibility
Gasoline was not invented since it is a natural by-product of petroleum. It is produced through the distillation of crude petroleum.
In an axial flow turbo fan engine there are two compressors. The first compressor is the low pressure compressor or it can also be referred to as the fan and is the first rotating assembly in the engine located aft of the engine inlet. The second rotating assembly located aft of the low pressure compressor or fan is the high pressure compressor. The basic difference between the low and high pressure assemblies is the amount of air pressure they generate. Low pressure compressors usually have a small number of stages and fewer and larger blades. Whereas the high pressure section has more stages and smaller blades. As the air passes through each stage of the compressors it is squeezed thus the pressure and temperature increase. When the air flow exits the high pressure compressor it is at its highest temperature and pressure generated by the cold section (compressor section) of the engine. Hot section/combustion section is another matter. Keep in mind that there are numerous turbo fan/turbine engines and each one probably will be configured differently as far as the number of stages and blades in each compressor section.
It may be done through measuring the pH valueof water
The water pressure is controlled by your pressure switch and the tank residual air. If there is less or low pressure with more than one faucet do a test. 1. switch off the pump. 2 drain the tank through regular faucet, then measure air pressure on nipple at top of tank, if it is less than 26-28 psi that is your problem and may mean the bladder is shot. It can be recharged with a small compressor to 26-28 psi. but this will only last a few weeks if bladder is faulty.The water pressure is controlled by your pressure switch and the tank residual air.

Gasoline is a major component to crude oil. This component is produced in refineries through the fractional distillation by subjecting crude to heat.
the sensor is part of the fuel pump assy and comes out through a hole underneath the matting in the trunk.... remove the cover and remove lines from assy and then remove assy from tank.....make sure to relieve pressure from fuel lines before you remove lines due to residual pressure in the lines...
