Raw Fuel on Top Of Sender Unit

My car has been in storage for a few months after taking it for a drive I noticed a strong gas smell. After doing a little digging I took the battery out and tray and was greeted by gas pooling up on top of the sending unit. I went over to pelican and did some research and it seems this could be a bad sending unit. They suggest draining the gas tank anyone done this without taking that step? It looks like a fairly straightforward repair minus the tank drain.

My 2000 was leaking gas vapors when it was 3 years old. Undoubtably the seal was bad, but dealer replaced the whole sending unit. I believe some part of the unit fastens at the bottom which is why you want the fuel level low. When the fuel level is low & the battery is disconnected the fuel level gauge will often lose it's calibration requiring a separate process & factory diagnostic tool to recalibrate the gauge.

You need to drain the tank. The unit sticking out of the top of the tank is the sending unit on a 986, the actual pump is bayonet mounted to the floor of the tank and needs to be disconnected from the sending unit and then rotated about 15 degrees to get it released, which would be very difficult with fuel in the tank.
