I have the opposite problem, which only occurred since I swapped clusters for a 996 cluster. Mine consistently reads optimistic, which I have concluded I need to go through the calibration process and that should cure my situation.
In yours, I would first pull out the sender, look at it, clean it, test the voltage it puts out, and see if that doesn't help. If the sender appears to be working properly, you may need a recalibration.

Okay, that is interesting. How does one perform a recalibration of the fuel gauge?
I might just go for this one.

Ask your dealer, its a very specific process that involves draining the tank, adding a specified level of fuel, and calibrating with the PST.

Porsche TSB for this
I've got the same problem on my 2000 S. The fuel gauge reads 3/4 after a fill up, sometimes goes up after a while, sometimes not. It seems to be accurate from 1/2 on down. Porsche has issued a Technical Service bulletin for this. It involves untangling some of the wires, hoses, and fuel gauge float in the fuel tank. It doesn't look to be too much trouble. I'll have a go at it Saturday and let you all know how it goes.

Ugh!
Well, most of the job was very straight forward. I pulled the sender unit per the TSB instructions. The fuel lines tied together with the cable ties were off a bit. I cut the ties and freed everything up per the TSB. However, after I had just about everything back together, I needed to disconnect a fuel line from the top of the sender again...and the plastic fitting broke.  Looks like I'll be buying a whole new sending unit. Damn.

Man, that stinks. 
Where were you able to access the TSB and instructions? My fuel gauge is getting to the point where it's no longer "quirky" to me, just plain annoying.
