Hey guys, having a problem with this 04 I35. Getting code P1456 Very small leak in the EVAP system.

1. Fuel cap has been replaced
2. No corrosion or rust around the filler neck
3. Ran a smoke test and no leaks observed
4. The canister and hoses appear to be okay condition

Any ideas on what to look for next?

 

Here is a link for the Infiniti service manual. Go to page 575 for info about P1456. They list a bunch of things to check.
