The first thing I would try is to carefully remove the wires from the sending unit, and give them a good cleaning.
Your issue might just be a little corrosion on the contacts, rather than a bad sending unit.

Try doing a search here in the projects section as there have been past posts (with photos) concerning fuel sender issues.
If you do plan to replace the sender, use extreme caution! The screws are aluminum and are easily broken.

I like add to check the fuel sender and tank grounds

I had the same problem and even bought a new sender because I was convinced that was the issue with my 2002. It turned out to be a factory harness connector in the stern section. Here's the detail you need:

I strongly urge you to check this out before you go too much further...

Same problem for me on the same year boat. it was my sending unit. There is a way to check them with a meter by moving the float up and down and studying the difference in measurements.

the sending unit was pretty cheap (I think 60 bucks) and fixed the issue. Was easy to replace.
