Hello, my name is***** and i will do my best to assist you.I am going over your story now and will reply back soon with some info,thanks!

Expert:  Lou P. replied 11 months ago.

ok based on the code, either the vent valve is faulty (coincidence) or a evap line was pinched when the tank was reinstalled. you will need to check the lines from the fuel tank to the evap canister to see what the issue is. hope this helps, let me know if you have more questions about this, i am not sure if you know what the evap system is or are doing the work yourself. Please take a second and click the stars at the top of the screen to rate me so i may receive my credit , 5 stars is ideal , please request me in the future.
Keep in mind then when you rate it does not end our conversation. you can still return here to me for follow up information if needed, Lou P.
