If yours has the Nylon fuel lines, like I think it should, they'll be fine. But the rollover valve and the hose to it would be good to replace. The valve can leak and the hose get brittle and leak as well.
If you have a skid plate I'd see if it needs to be cleaned to get trapped dirt off it that will eventually rust it out. And put anti-seize on the threads thereof.
