Oh that's definitely interesting...so it's been an issue for a while now. Wonder why they never fixed it / realized the issue on the 350z? They could have saved themselves the headache on the 370s.
To answer your question, we looked at where we could move the EVAP canister, and there just was no way to move it anywhere else that would help. Other than starting to do some bodywork on the rear bumper to MAKE it work. Moving it to the middle would interfere w/ the canisters, too.
Anyway, hopefully I have some news coming soon about it. Still working hard on the issues at hand
There's plenty of things I need to fix on Rin before she's back to 100% haha
