For those with EVAP codes...
If you're experiencing a CEL resulting from EVAP faults (EVAP Leak-Large in my case), then check the big O-Ring/gasket on your fuel pump assembly. My car was throwing off a code for a large leak and I knew something was fishy since the gas had caused the ring to expand a little, to a point where it wasn't fitting the groove causing the fuel pump assembly not to seal correctly. I replaced the ring and reset the ECU. Problem solved.
I would definitely check this since it's super easy and cheap ($8) instead of replacing your canister, gas cap, etc.
Just my .02.

this is a great piece of advice. I was driving back last weekend when the SES light came on, pulled the codes and it was a 1448 and 0445 code- "gross leak" with EVAP.
where is this fuel pump O ring? I know the fuel pump is under the passenger seat...any directions or pics is most appreciated. I did reset the CEL but it came back after about 20 miles...same codes...I checked the rubber tubing and canister in the rear which looked perfectly fine...so I am suspicious it could be what you mentioned with the O ring.
thanks!

After you remove the rear bench,
1. Disconnect the plug to the pump.
2. Unbolt the three bolts.
3. Remove the 6 screws and the fuel piping.
There should be a big-ol o-ring between the fuel pump assembly and the fuel tank.

Might also wanna include relieving fuel pressure, just to be on the safe side.
