Gas tank leaking #%*!!

Here's why what?? That's the tank-level sender and fuel-return line, not the pump. If it was wet around that fitting (in the well) then that is the non-uncommon leaky gasket for the fuel tank sender.
Step 1: Exhale, then a couple of deep breaths. You didn't blow yourself up disconnecting the ground strap so everything will be OK. Wrap the ground strap in a rag or towel so it cannot accidentally ground, and leave the batery alone-- it is functionally disconnected.
Step 2: You will need to siphon off some gas, to get the level below that fitting. Maybe a single 5-gallon jug, not sure. That should also stop it from leaking (assuming that is the only leak-- which is very likely).
Step 3: Order a new gasket (928-201-327-02), and maybe a new plastic nut (113-201-375-01C), around $20 total from Roger, 928 Int'l, or any Porsche dealer.
Step 4: With parts on hand, remove fuel-return line and electrical connector (carefully pull straight up), remove nut, remove and replace sender with new gasket, fit new nut, torque to spec, replace connector and return line.

I sacrificed a old towel , soaked it in water and completely sealed off the
sending unit opening
I have no problem replacing the union nut or the gasket
The fuel gauge was acting wonky, not indicating a full tank and
fluttering when I shook the wheel hard
But after I cleaned up the original gas, there was more present
This will require more investigation
I'm off to get a siphon and a gas can
Thank you for the prompt response

The fuel level is above the sender fitting (the tank extends up into the right-side fender, above that fitting level). Once you siphon out a few gallons it will stop leaking.

Got a transfer pump/siphon, extracted 4+ gallons
I used a oil filter wrench to loosen the union nut...surprise, no gasket
so gasket ordered and an inspection / cleaning of the sending unit
I thinks it going to be all good
Thank you Jim

Warm up the plastic nut to make it easier to reinstal, and a bit of lube on it will also help. I managed to clean deposits off the resistance wire with degreaser or similar.

Incredibly helpful tip, I tried a couple of dozen times to get the plastic union nut
to fit over the sender with new gasket...no joy
Tried with the sender out and it was a bit fussy, needed to be lined up just so
thank you mr. pitman, thank you
