My 06 was like that and I adjusted the fuel sender in the tank and now the guage indicates correctly and drops in a linear way. When the reserve starts indicating fuel needed I put in 5 gallons. Just about right because the manual says there is a 1.6 gal reserve.

There is a great post that shows you how to do it. I found it on fjr13.org listed under "adjusted fuel sender" Or you can Google
"adjusted fuel sender fjr13.org" I did exactly the procedure laid out and the results were great.
I used a new seal/o-ring on the fuel sender when I did it. Also covered the painted surface with blue painters masking tape as you have to work from the bottom and you have to massage the sender/fuel pump assy. out and then back in.
