Okay, I changed out the fuel pump module in my 2001 Blazer yesterday, and now the vapor canister is filling with fuel. All of the lines were reattatched in the same places they came off of, and when I remove the line from the tank to the canister at the canister end, fuel runs out of it after the truck has been running for a minute or so. This line from the canister goes to a check valve on the top of the fuel pump module, the other to the purge valve on the intake, and a third large hose to the vent valve (best I can guess at the actual component). I have seen an overfull tank run fuel past the check valve, but since the swap the highest fuel level it has had was just over 1/4 tank. Anybody got an idea on this one? I'm lost. Any help is greatly appreciated.
