I got BAD fuel in my below deck tank.

Re: I got BAD fuel in my below deck tank.

phase separation starts within weeks on e10 if it sits. it takes the constant agitation of a return fuel line to prevent it.

Phase separation only occurs when more water than the ethanol can keep in solution gets into the tank; time per se has nothing to do with it.

If it still smells like gas, burn it up. if it doesnt, get a fuel siphon pump and change it.

Siphoning the fuel out of the tank's outlet fitting isn't going to work if (if) the tank has an "anti-siphon' valve... You have to pump it out if going through the anti-siphon valve. Or, if you have access to the fuel tank fittings, remove the anti-siphon valve, attach a regular barbed hose fitting and pump the tank, then replace the anti-siphon valve.

You can pickup a cheap electric fuel pump off Ebay $30. I bought a 25' roll of 5/16 fuel line from Checker Auto a couple years ago for $25, been using it for lots of things including pumping out the boat tank. (Just don't use that fuel line for repairing the boat, not USCG approved.)

When I needed to drain my tank on the old ski boat I bought all I had to do was remove the fuel line going to the outboard and use the syphon bulb like I was pressurizing the fuel line and it syphoned the gas out and into a container I had for disposal. It got most of the fuel out and from there I used some seafoam an filled it with good fuel.

Re: I got BAD fuel in my below deck tank.

A few years ago I got a ton of water in my tank. Long story..... anyway here is how I solved the problem. I went to Academy (you can probably find them elsewhere) and purchased a hand held siphon/bilge pump. Its made of plastic and rubber and has no parts that can spark or create heat. On the gas tank I removed the fuel guage sending unit which gave me a small whole to work through without having to worry about antisiphoning issues. I placed the pump in the whole and went to work! I had about 30 gallons of fuel and 5 gallons of water. I did notice something that may interest some of you. All the water was at the bottom because the water is heavier than gas.....right? So I probably could have stopped once I started getting clean gas, but I continued because I had put all sorts of chemicals in the fuel trying to get rid of the water. Anyway, when I was done, I threw away the pump thinking it would be ruined in a few hours since it had gas in it all day. Total cost.......about $20.00 not including the 55 gallon drum I borrowed to put the gas in.

If your unsure, just get rid of it. Hurry! Good ole' gas aint a getting any cheaper!

if it's not that bad but is affecting your confidence, you can still burn it in the car, so you haven't wasted anything but your time.
