2000 Monte Carlo SS 3.8
Can a bad or defected EVAP canister be the cause for gas leaking while you pump and also my SS spits/chokes and acts like it wants to shut off if I pump more than a half a tank of gas, what can that be?? Help.

I think your on the right track, but typically the symptom of a clogged EVAP canister is the gas pump nozzle constantly shutting off as you try to fill the tank, as if the tank was topped off. I had that problem with one of my '00 SS's until I replaced the canister. It didn't effect engine performance. You might have a problem with the EVAP vent valve, the hose between the canister and the vent valve, or one of the EVAP lines out of the canister. Where is gas leaking from? Near the driver side rear wheel well behind the tire, or forward of the fill cap under the car (between the gas cap and rear of the drivers door)? Can you see what piece it's leaking from?

That's the EVAP vent valve by the rear wheel. If your having trouble filling, the EVAP canister needs to be replaced. The fuel tank needs to be dropped to get to it.
Here's a video about the canister:
Here's a video with a vent valve on a pick-up, but the principles are the same.

I think you have a bad EVAP vent valve. It can also cause the nozzle to shut off. Gas wasn't leaking when my EVAP canister was clogged. The vent valve is easy. Remove the rear wheel for access. Remove the bolt that secures the clamp holding the vent valve to the car, remove the electric connector and hose and take out the vent valve. Reverse procedure to install.

someone said the vent valve under the hood next to the motor could also be the problem did you have to replace that piece as well??
