Water in fuel tank

Hey,

Has anyone had issues with water finding its way into the tank. I just went on a trip (without a rain cover) and my bike sat out in the rain all night. The next morning it stalled out and I ended up needing a tow. The tank had water in it.

I'm guessing I have a fuel cap issue. Anyone else have this issue?

Doug

Looks like a mess. Did you happen to just purchase fuel when you parked it for the night?

No..but I was on reserve. Is it possible that because water is heavier than gas I had water in my tank from a gas station and it only affected me when I got low on fuel and hit reserve?

The K bike K12/13, don't have a stand tube like older style bike fuel systems where you rotate a petcock to reserve and now have access to the last of the fuel. BMW just says reserve, meaning a point at which the yellow reserve fuel is now being used. It is all one large sloshing gas tank. Also your bike has only a fine mesh shock at the fuel pump intake. You probably already have but if not, it would be a good idea to research how to open your tank up (off the bike) and dump out everything and clean the tank with some fresh gasoline. All a big mess to do but worth it. So it is possible for this to build up a little before you reach the suction of the pump but not much. Time to think about both your lid seal and where you purchase your fuel.

Water in fuel

There is a fuel tank cap cavity drain. Its a small hole on the side of the seal that the cap sits on. It connects to the rubber hose to drain the water at the bottom of the engine near the kickstand. I have found my drain lines plugged up with dirt and or a spiders / bug dirt nest several times. If the water that gets into that cavity cant drain, its going to find a way into the tank.

See if you can blow through that drain hole. If not, get it unclogged.

Are you sure your gas cap was closed correctly? The gas cap will close , but until you hear the "click" its not closed all the way.
