1987 Spectrum - fuel flow from bottom of EVAP canister

1987 Chevy Spectrum, 40,000 miles, AT, 1.5L

Car starts and runs fine, but fuel flows out the bottom hose of the evap canister.

I don't know if the carb float being stuck open might cause this, but the site glass fuel level is below the half way mark, where I would expect it to be full to the top with a stuck float.
