I have a jet ski that has stale gas, looking to pump it out, saw some ways to do this here, just don't remember
 
How statle? Most of the fuel systems of the past bunch of years are effectively sealed and the gas stays good. I'd add some octane boost, if it does run okay, and enjoy the ride. I'd expect gasoline left for two or three years in a sealed system to be good to go.
 
I would siphon it out with a manual hand pump the most you could have is about 16 gallons.

Look at the Arnold Siphon Pump I have one from Harbor Freight I think I paid about $3. At the boat show there is always a guy who sales a siphon tip for a hose that would be great for this job. You can add the old gas to your car a little at a time it will be fine.

Depends on if it was treated. I treat everything except the car.

I use StaBil. Double dose.

My experience:

1 year no problem. 2 years is OK but you can smell it starting to go bad. I would not trust 3 years but have never gone beyond 2.
 
Siphon, but remember that gasoline fumes are explosive. Don't use anything electrical and do this away from buildings and vehicles.
 
If it were me, I would use a hand siphon pump, which is what i suggest for you Walter.

For others though, I might suggest bringing the jet ski into the engine room of their gas powered boat. Then bring in their portable Honda Generator and plug their shop vac into it and suck the fuel out.
 
Whatever happened to the good old days when you would do it by starting a syphon by sucking on a garden hose?
 
The gas is 2 or 3 years old, just figured it would be better to get rid of it rather than have a potential problem. Thanks for the suggestions and the hand pump looks great.

"Whatever happened to the good old days when you would do it by starting a syphon by sucking on a garden hose?"

Yup, that's what I did as a kid, the thought though of getting a mouthful of gas is not to appealing anymore :)

I use one of these.

Works like a champ for about $5-$6 at HD.

OH and Walter....getting a mouthful of gas was not to appealing then....we were just dumber.
 
I wouldn't use 2-3 yr old E10 stored in a vented marine vehicle tank even if it had been "stabilized" when brand new.
Low octane allows detonation to melt pistons.

An outboard fuel line with primer bulb that has the ends removed works nicely to start and keep a siphon flow down into a gas-safe container at lower level.

Or you can buy opposite mating fittings that essentially open the ends temporarily...

I have one of those siphon tubes that you shake to start the siphon. Got it at Lowes for less than $10.
