Does anyone know what the difference is between the fuel filler neck on my 2005 350Z:


And the one for the 370Z ?


The fuel caps are different between the two, as well.

Here's my issue: when I tried to siphon the old gas from the Z when I bought it in 2018 (it had been sitting for about 2.5yrs), I damaged the flap that closes off the fuel filler opening. I think this is causing my check engine light (code 0455 EVAP leak). I want to replace the fuel filler neck and am trying to find a suitable parts car (or if someone has one in their stash of parts to sell, send a me a PM). Depending on the differences, maybe I can use the 370 part? Or, if using the 370Z filler neck I would also have to change to a 370Z gas cap? Inquiring minds want to know!

Thanks for any help!

Don't believe that's your problem. The flap isn't air-tight. The cap is what seals the neck. Your leak is elsewhere. Have someone do a smoke test.

next time on the passenger side behind the seat open the storage compartment and in the bottom is a access to the fuel tank

Yeah, I'll take a look at how things are through there, too.
