Best way to get Water out of gas tank??

I'm looking for options to get water out of the gas tank & fuel lines WITHOUT dropping the gas tank. I live in an apartment complex and don't have the means or space to drop the tank.

I've heard a few people mention Sea Foam or Denaturalized Alcohol...anyone have any luck with either of these??

I was thinking about emptying the tank and using some sort of additive.

Thoughts/Opinions are greatly appreciated!

Have you tried a bottle of Heet? It absorbs the water and acts a gasoline anti-freeze. Worth a shot at least. You can get it at any local auto parts store.You could also pull the fuel filter loose and let the gas pump out into a bucket...away from heat or sparks.

I guess the main question is how much water?

Just a little, heat or seafoam should do.

A lot, you may need to drain it at the fuel filter (if it's enough that the fuel is no longer usable at all).

Haven't tried HEET. Haven't tried anything for that matter, yet. I did just pick up a bottle of Sea Foam though. Hopefully this works. I ended up with some water somewhere while I was wheeling over the weekend. I'm thinkinking there is definitely water in the fuel...

I'm really not sure how much water. Enough to make my Jeep sputter when giving it more than half throttle while in gear...

I got in a sticky situation for less than a minute. Can't imagine too much water could have got in anywhere??

What exactly did you get into? Did your jeep start sputtering after that incident?

Denatured alcohol or HEET is what we use up north here... the water in the gas happens every year usually un the fall up here. I had the same prob last year till I dumped the old gas, dried out the tank, and ran a few cans of HEET thru it. You might wanna try about 3 cans first, its only about $2 each can. That way if it works, you don't have to drop the tank.

If you are looking to get rid of the gas you can pull the hose at the fuel rail and jumper the fuel pump relay. I don't know how much gas you have in it but the fuel pump will empty a full tank in under 10 minutes.

I was up here in Alpharetta doing some light wheeling. Found some failry cool trails -- ran across a mud puddle that happened to be much deeper than expected. Muddy water up to my floorboards!!!

everything seemed fine until I got off the trail and back on the road. It was sputtering BAD. put some gas and fuel system cleaner in the tank, and it drove fine for about 5+ miles before the sputtering came back.

Maybe the cps is crudded up? How empty was the tank & did you fill it? If that is the breach you need to fix the leak too if its not the cap.
