EVAP leak detected?

[eepp]

Hmm I might have done this in the past, yes.

I also sometimes fill the tank while the engine is running. Is this bad practice?

What do you think IS the EVAP issue here? I know this has many components and pipes, but how topping off could cause a permanent issue like a leak?

If I get this donut gasket fixed, what's the problem with having an EVAP leak, except for pollution?

I believe most cities it is illegal to gas with the engine running. Not sure of the fire risk but apparently there must be some.
As far as you EVAP failure, it will cause worst mileage which may clog your Catalytic converter which are quite expensive. The reason topping off is bad as it floods your EVAP system.
