Fuel fill neck width for 22ZX
 

I'm interested in changing to a new fuel fill and billet cap. I'm not sure if my 2001 22ZX has a 1.5" or 2" neck. Does anyone know the best way to find out what the stock dimension fuel fill neck on my ZX is? I don't know of any way to contact Donzi directly. If I called a dealer with my hull number would they be able to tell me? The boat isn't near me know and I hope someone can point me in the right direction.
