Slow gas gauge

I have a 94 LS400 here and the gas gauge is VERRY SLOWW. Is the problem in the gauge itself or does any body know what else it could be?

I see your question was ages ago so you've probably taken care of it by now but for anyone who's asking in the future: I was told by my professional mechanic friend that the LS (and other luxury liners) fuel gage moves very slowly so it won't show 1/4 tank when you turn left, then 3/4 tank when you go right, etc. In other words, it reads the fuel when the car is level and if fuel is lapping around a bit in the tank at all it will cause it to read slower. Mine on my '90LS is really slow too.
