Nix on the shop vac. The interior of the motor is exposed resulting in electrical sparking in a gas vapor environment - explosive in other words.

I'm pretty sure they disproved the shop vac thing on mythbusters......still i wouldnt use it when a siphon is prolly the best practice anyways

Re: Extracting old gas

I recently drained 25 gallons from my tanks. here is what I did:<br /><br />Went to local auto parts store and purchased the cheapest electric fuel pump they had ($19.99) The pump has a 3/8 inch inlet and outlet. Hooked the inlet to the outboard's fuel line coming from the fuel tank, and hooked a 4' piece of hose to the outlet side of fuel pump. I installed alligator clips to the electrical wiring and hooked it up to a battery. Drained 25 gallons safely and quickly; plus, I can use it over and over if needed. Sure beats worrying about fire or explosion.<br /><br />Then I used the old gas in my Dodge truck. It did not even burp!

i used air pressure from a compresser forced into the fuel vent line, it presurised the tank and fuel came out the fuel line real fast.

What do you do with the bad gas? Here in arizona it costs big bucks to get rid of it.

Try like about $4 a gallon!<br /><br />Unless the tank is contaminated with something, Use the gas up. Add some Pri G to it, add some fresh fuel and go.<br /><br />If you are really anal about it, call your friends and neighbors and have then bring their gas cans. Fill 'em up and let them use it in their mowers or whatever.
