There was a technical service bulletin on this for some models. The float arm would get tangled in some of the wiring, and the TSB basically says to zip tie the wires out of the way. The float mechanism isn't too tough to get to; the job can be easily accomplished in a couple of hours. I'd suggest driving the car to almost empty before tackling it, just to minimize the amount of fuel you have to work around.
Be careful undoing the snap-connect fittings from the plastic nozzles on the top of the fuel sending unit...the nozzles can become brittle.
