I had that same code a cpl years ago//turns out it a small leak on the non pressure side return line...at the connector to the top of the tank...(rusted out)
I had to replace the lines as well as drop the tank and replace the pump etc...
problem resolved...

Switched the gas caps to a GM new one, but the code kept coming on.
Usually 1st it was tighten gas cap, then after tightening it the code would come up.
i just returned from the mechanic today that i trust and he said he tested it and i need a new vent valve solenoid.
So its going back to the shop tomorrow for him to change.
generally i would attempt to change it myself, but i just dont have the time right now.
ill post back when i have news.
