How do you siphon gas from a common passenger vehicle if you have bought several gas siphons from hardware stores the hand pump and the push pump and you can never get them to work?

Answer

The easiest way to siphon gas without getting a mouthful is to use a long, clear hose. Put one end of the hose in to the tank to siphon from. Now let a loop of hose go all the way to the ground and then back up to a level higher than the gas in the tank. Blow on the hose and listen to be sure it is in the gas. Now suck on the hose until you see the gas come out and start down the hose. You can remove your mouth as soon as you see the gas heading down. The gas will travel through the hose and up until it reaches a level even with the tank. As you lower the end you are holding up you will see the gas rise in the hose. As soon as the end is lower than the level in the tank it will begin to flow out of that end. It will flow as long as the end stays lower than the tank level and the other end stays in the gas. It's a piece of cake once you have done it and see how it works and it will save you from getting a mouthful.

Sorry, but that does NOT work anymore as the filler necks have a check ball installed in case the car turns over then no gas will spilll out.
