Fuel top hat broken?

[ZinEU]

I have a 2009 370Z and i'm having the common problem of fuel cut off on right turns on WOT. It started about 3 months ago and ive just been dealing with it by keeping a full tank, but ive finally had enough so im trying to get to the bottom of this now. I've researched on here but i cant seem to find an answer for my exact problem. I've owned the car for 4 years and i've never had an issue with fuel cutting off until recently so im ruling out fuel starving and im assuming its somthing failing. My best guess is the fuel top hat has a crack. Is there anything else im missing? The car starts fine and on WOT its good so it cant be the fuel pump. Just on right turns on WOT id say below 3/4 tank. Thanks!
