Does anyone work at a Ford dealer that can get a window sticker for me?

Scroll down to the line that is labeled 720-03-01. Compare with the following

720-03-01 xxx5 54xx xxxx 36 Gallon Tank
720-03-01 xxx3 67xx xxxx 23 Gallon Tank
720-03-01 xxx3 D9xx xxxx 26 Gallon Tank

YES! Thank you!

That line reads 2805 5400 00AC

36 gallon tank confirmed, I think.

Are you a Ford technician?
