I am in the process of replacing my EVAP Charcoal Canister (2005 Tahoe). I removed the canister and loose charcoal bullets poured out. Having issues with filling the gas tank was led to this as possible cause. I think replacing appears to be the right thing to do.

I have ordered a replacement on line. Would it be ok to drive the vehicle for a few days without having the canister in place. Or should I reinstall the old canister until the new one arrives.
