The fuel gauge on my Beneteau 311 is stuck. I believe it is a faulty sending unit in the tank. How do get to and trouble shoot this sending unit?

Welcome to the site. Around here, we require the poster of questions like this to first do a little work on their own and then we can open our combined encyclopedia of knowledge to them.
First, we need to know the make of the sender and gauge readout you are looking at. Beneteau tells us nothing as the type of gauge used on Bene's will change from year to year. Can't see a label ? photo both components UP CLOSE.
Second, describe exactly what the problem is ie. stuck at 100% stuck at 0% or somewhere else.
Third, any other info you can offer as to what else is happening such as when this first occurred, etc, etc.

Let's look at the problem first before jumping to uninformed conclusions and finding it's a corroded connection.
Here's a couple pages with guidance on testing the sender, getting to it is sometimes accomplished thru a panel in the aft cabin if lucky, or diving into the aft lazarette head first if not. Last time I had a problem it was the gauge and not the sending unit.
To Test the Gauge:
With power running to the gauge, disconnect the sending wire; it will be marked with an “S” at the back of the gauge. Once the wire is disconnected, the gauge should jump to its highest possible reading. If this is the case then the gauge is good and you can proceed to the next step. If the gauge does not reach its maximum reading, it is faulty and must be replaced.
