Under the back seat, there's a round cover. Take that off & you'll see the fuel tank with another round cover. Electrical connection & 2 fuel hoses.
Make sure your fuel is 1/2 tank or less, that cover isn't really the TOP of the tank. You don't want to unbolt it & have 3 gallons gushing out.

#1 is the fuel pump, #30 is the cover under the back seat. Notice the big high part of the tank behind that opening? That's the part you DON'T want full of gasoline...
