When a mechanic wants to empty the gasoline tank of a car he fills a plastic tube of gasoline dips one end of the tube into the gasoline in the tank and puts another end into an empty drum placed lowe?

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).


When a mechanic wants to empty the gasoline tank of a car he fills a plastic tube with gasoline dips one end of the tube into the gasoline in the tank and puts the others why does this technique work?

t will work if only half the tube is filled so a column of air will be trapped between both ends. As the gasoline in the tube flows out of the tube, it pulls the column of air between gasoline and the other end inserted into the tank creating a suction effect. The empty barrel has to be lower because as gasoline inside the tank is drawn into the tube, gravity has to take over to make the gasoline flow downward.

If gas tank is empty for a week would fuel pump fail?

You must remember that (in tank) fuel pumps get lubricated by gasoline. If you run out of gas and keep trying to start the car with no gas in the tank....then the fuel pump is spinning without lubrication. So the pump can lock up. I see that occasionally here at my shop. However, if you put in enough gas to submerse the pump then beat on the gas tank with a baseball bat then the pump will sometimes free up and work again. If your gas tank has been empty for a week but you havent been trying to start the car with no gas in the tank then you will probably be ok. If you ran the car out of gas and kept trying to start it then the car sat for a week, then you may have problems. It all depends on the conditions that caused your empty tank and what you did after you ran the car out of gas.


When a mechanic wants to empty the gasoline tank of a car he fills a plastic tube with gasolime and dips one end of the tube into the tank He puts the other end into an empty container which is placed?

It'll have to be at a lower level than the car's gas tank, although, in reality, he would have to remove the fuel tank, disconnect the neck (as modern cars come with an anti-siphon neck), and either place the fuel tank at a higher point than the receptacle, or else use a vacuum pump (with diesel fuel, it's fine to use an electric one, and that's what we do at my shop.. gasoline is much more volatile, though).
