The 20XD is a different animal.

Siphon as much fuel as you can get out of the tank. Then tape off the fuel fill and vent openings. Lift the back (live well side) of the tank up and pull out on a angle.. It is a little easier with 2 people till you place a few straps under the tank for future removals.

Be sure to ck/replace all pumps and hoses while tank is out.
Hope this helps
