McRaymond3,
How exactly did you empty your tanks. I have a reversable hand pump that we used for race gas drums, but I cant get a hose thru the fill. I guess I could take the pickups out and get to it that way.

I'd say to store it however you want but realize that fuels we have today don't store too well and I'd think that you would want as much of a fresh fuel load as possible in the spring. --- JP

Viper 31,
I haven't emptied the tanks yet. The motors aren't in the boat. I have three tanks and three switches in the bildge that when I switch them on, it pumps fuel out of the lines.

Re: Draining the old gas?
I never believed in filling up in the fall, I have always left as little as possible in the tank over the winter.. I would rather have 100 gallons of fresh gas in the spring, than 100 gallons of 6 month old stabalized gas.

Re: Draining the old gas?
I always fill mine to the top. Used to run them low but everytime I had problems with the fuel sender guage. They would rust and not work. Had to pull them out and try to free them up or just get a new one. No problems with a full tank. Lets face it the first tank is wide open.......right? A good excuse to burn off that old fuel!

Re: Draining the old gas?
I always filled and stabilized mine and never had a problem. I'm usually only winterized for about 3-4 months. One problem with filling up is when you get an abnormally warm winter day, the gas expands and it spills out my vent.

Re: Draining the old gas?
I believe that it takes longer than our 4 month winter for the aromatics to flash off. The time is somewhere in the 6-8 month range. That shouldn't affect most of us. Of course, I'd highly recommend AudioFn and Too Old to totally drain their tanks. That gas will revert back to crude before they use it.
Hyper-you are proably refering to the alcohol damaging the rubber parts. That is true with straight alcohol. We have a very tiny portion of alcohol going into the tank and it'll be ok.
