Help from my 370z brothers
 

Fuel filler hose, Part # 17228-1EA0A
shown as part #7 in the diagram.
I'm told it is on a national backorder, and no production release date in future.
Called 20 or more dealerships on east coast, noone seems to have one.
Anyone here with a parts car lying around??????
Know of any in a local scrap yard???

Did you try any of the online parts places? Contact them to make sure they can get it first. I've used scrap yards before too, when I needed a connector for the main harness.

Ended up finding one in a scrap yard in Michigan. What a ridiculous search....
There was another in Calif, but they wanted to sell the entire filler neck with it, and would not separate them.
My last resort was going to be a stainless flex coolant hose.
