Fuel cap leak

[sonex293]

The fuel is actually coming out the vent tube not around the/through the gasket. Probably doesn't help that its a nosewheel.

Anytime you do a slip, skid, or other uncoordinated flight maneuver the fuel in the tanks will slosh sideways and very likely burp some out of the cap breather vent tube, especially if the tanks are nearly full. Its a nuisance that can't be helped if you are like me and do a lot of intentional slips. I have to wipe down the wings aft of the fuel caps after almost every flight or two, otherwise a fuel stain will start to show.
