Draining a Gas Tank Problem… Drawing Included

[moonman43]

I'd like to offer my 2 cents worth. If the gas tank is not too deep you can use a turkey baster to suck out the remaining gas and then let the tank air dry in an open area as one of the others suggested. Using a rag will present another kind of problem, especially in an apartment. The fumes will last longer and that will give you something else to dispose of. With the turkey baster you can let it air dry along with the tank and wash it afterwards.

Just trying to be helpful. Keep the rubber side down.

Aren't there something like 4 different ones?

If there are, I'd certainly like to know. I got both of mine off Limewire and I never saw a third or fourth.

If I rinse the inside of my tank with water, how necessary is it for me to use a sealant before I start using the tank again? It doesn’t look too dirty to me. How about if I rinse it with laundry detergent + water?

A friend suggested I could simply rinse it with gasoline a couple of times before reinstalling it and I should be good to go. I know a POR-15 kit is the best thing to do but I wonder if I truly need it at this point.

What do you guys think?

I'm not an expert here - but it either has some rust in it or it doesn't. Once the rust has started - even if it's just a little, it won't just go away - I'd go ahead and seal it up properly to keep from having to repeat this whole process in the future. And if you say the gas had rust in it it's almost certain you've got a rust spot in there even if you can't see it. Do it once and do it right and you'll never have to worry about it again.

point well taken.... pro-15 it is. the price and my inexperience scared me a little, but i think you are right. no sense in not trying to do things right. ill heed your advice and follow the kit directions very carefully.

oh man now im confused. i defenitely dont think there is much rust on the inside, other than some minor discolorations on the metal, so the Yamaha Fuel Tank Conditioner Kit may be the way to go for me. plus the petcock has some sort of filter attached to it, and i dont see much rust or debris on it. I guess my concern was that soap+tide would ruin the sealant already inside my tank, but this doesnt seem to be the case.

Yeah - I didn't necessarily mean the pro15, just that once rust has started it won't stop without some kind of interior tank treatment. What Norman suggested may well be enough. I can't see the inside of your tank. But I'd definitely do something chemical to counteract whatever rust you have.
