What carburetor do you have on this?
Continuously overfilling the fuel tank, will eventually fill the canister, with liquid fuel. There is a small expansion tank, above the fuel tank, behind a body panel, in the rear cargo area, in the area behind the right rear tire, that allows the fuel to expand from the gas tank and then flow back to the fuel tank, when it cools down. There is a pressure relief valve, between the expansion tank and the evap canister. When the pressure in the fuel tank gets past a certain point, the vapors in the expansion tank are vented to the canister. If the pressure gets too high, while the expansion tank is full of fuel, raw fuel goes to the canister, instead of fumes.
Over fill every the gas tank every time, the expansion tank is overfilled time and again and the canister eventually becomes fuel soaked. Not very common. (I've got one I took off a 1971 Toyota and its still good) The pressure relief valve can fail, too, but shouldn't result in the evap canister becoming completely fuel soaked. If when you put fuel in it, and removing the cap releases pressure, the pressure relief/check valve is working properly (for the most part).
Considering your engine died, I would look at stuck carburetor float, instead. The evap canister vents to the float bowl. If your float sticks, its possible for the overflow of fuel to flow back down to the canister and viola, flooded engine and "leaking" fuel canister.
I wouldn't replace the canister, yet. Figure out where the fuel is really coming from, fix it and see if it all gets back to normal.
