I am the original owner and that part had not been replaced. I only purchased the solenoid valve itself and not the kit. Since the truck is not subjected to being overfilled or dusty conditions I am rolling the dice. The line to the canister was dry also. I did manage to replace the old solenoid with the new one yesterday. In all the sites I have researched for this isssue I do not recall anyone saying they found the solenoid to be split or cracked but that is how I found mine. It looked as if it was filled with water, froze, expanded and split. The engine light went out after about 2 miles of driving and I think I am good to go. Once again thanks for your imput. I try to do as much of my own work as I can and if not for these web sites and the knowledgable that participate on them I wouldn't do nearly as much myself as I do.

Maryland does require emissions testing. When I went there to extend the due date I asked them if they could test the cap. They wouldn't do it because the cap is not tested on the 04 and they had no base line to know if it was working or not. I think you're correct that most likely it is not the cap. Thanks for the feed back.

I have heard the cap can be pressure tested. I called a few parts places but they didn't do it. Any suggestions where it can be done? Thanks for your help.

After reading several forums about emission codes PO 455 & PO449 general conscenus is the EVAP vent solenoid goes bad due to over filling the tank. My tank has only filled maybe 3 times since 04 when it was new. Any thoughts on maybe the fuel cap it self is actually bad? Also, do you have to loosen and lift the bed to make enough room to remove the solenoid? On the 2004 standard long bed trucks it is between the bed and the cab?
