I was looking for a 36 gal tank for my 2013 SCREW. On ford parts they list a different tank for vehicles built after may 2012. The tank for later models is substantialy more expensive than for pre May 2012. does anybody have any idea what changed?

I was hoping to get one from a scrap yard, but if I'm limited to vehicles less than a year old, chances of finding one get real slim.
