Did you replace the gas cap with an aftermarket one from a auto parts store or is it an original OEM cap?

I've had issues with non OEM caps causing evap codes on previous vehicles.

As for the lines going to your tank. I think you would be looking at dropping the tank to be able to access all of the lines on top... You might be able to poke around the charcoal canister lines and see if anything is clogged.

I had a fuel tank spring a leak on me once because of the chemicals dropped during the winter literally had eaten the metal on top of the tank... It was a PITA of a job. Hopefully you wont need to do any of that.
