Yes, the tank schematic is from jdparts for the 3320. Should look exactly like that. Poke around at that site, and as well, get yourself a copy of the service technical manual for the 3320. Well worth the few bucks..
And...
I wouldn't trust the fuel even if it did "Look" good. At a minimum, drain the bottom of the tank.. keep it in a bucket or old fuel can so not to dump it on the ground. Just not worth the risk...IMO. If there is sludge and bad fuel with possible algae, I wouldn't want to push it into the fuel pump and injectors.
I would also have picked up a Deere battery of the same rather than one with "similar" specs and sizing. Not much room for error if it is like my 4300. Deere products are good. Scrimp somewheres else.
But it sounds like it is yours to do with what you want.![]()
Done.
When I go to pick it up old fuel out new fuel in. Probably spin a new filter on too? You have online place you like to get stuff like that??
