Hi all,

mine is an 06 B11. I've noticed after washing it the last few times, water remains in the fuel filler cap. The drain hole is obviously blocked.

My question is, do I unbolt the filler cap itself or remove the tank and work from underneath? The parts manual doesn't show the drain line at all so I need to be sure I'm not going to accidentally unplug it if I remove the filler cap which is the easiest step to begin with.

cheers

Robert
 
Tablet 13 in the parts book shows the gas tank vent/drain system.

Remove the seat and right side cover to get to the T connector. I bet that is where the clog is. Make sure the hose is not kinked and flows down without any traps or bowl shaped hose runs. You can try compressed air but you risk popping of the hose under the tank, then you'll have more work to do to reconnect it. First I'd test the drain by pouring gas down the tube inside the gas cap that way you'll see if it's making it to the T when you disconnect it.
 
Thanks Rafael.

I did see Tablet 13 but didn't realize one of those pipes was an overflow (late night reading I suppose).

I will do as you say as that is an easy option.

Much appreciated,

Robert
 
Hi.

Unser the tank there are 2 Brass unions. I fond that these block more frequently than the plastic T under the seat.

You can thread a bit of wire through the hole under the filler cap to try and un block it. If not it's time to lift the tank and un screw it. (Use the rubber drain pipe) then unblock the brass bit.
 
Update

It was a tank off job. The connector that protrudes on the underside of the tank where the drain pipe connects was blocked with crud. Bit of wire and a flush and all is good now.

One thing I did encounter, when I reconnected the fuel line, I didn't hear or feel the click at the base of the tank. I fired her up and no fuel leaks so I'm wondering if I should hear/feel the click or not. I can pull it apart with a good tug but it seems to be OK.

Should I revisit it or leave it?

regards

Robert
 
If you don't have to manipulate the grey ring to remove the fuel line, the connector should be replaced. You don't want it coming off and pumping gas all over the bike under your seat. Not only will the engine die in short order, it could make for a very hot ride!!
