I dont have your model, but I would venture to say that while any mod is possible. It comes down to what is needed to make it work. I.E. wire harness. The digital speedo will most definitely have a different wire harness for it.
Best thing to do is concentrate on the electrical compatabillity rather than worrying about changing tanks. Which btw will prolly have to be done as well.
Just tryin to give you somethin to think about.
