Gook luck with yours Mike S.
To summarise the steps I now believe are required to do a quick external fix:
1. Clean area thoroughly with a small paint brush and brake cleaner spray
2. Remove the plug from the sensor terminal. Clean a bit more if required, esp. around nut.
2.a You may wish to make some room by disconnecting some of the loom and holding it away with a bungee
3. Remember (photo) where the nut sits for reference. Get a tall 32mm socket.
4. Undo the nut about 2mm (2 turns?) only. Pull sensor upward to verify - this gap guides the PTFE in.
5. Feed in 24" (or so, this is an estimate) of thin plumbers PTFE so it grips and gets right down into the channel below the thread. This is a 2 handed job as you'll need to keep the tape low so it feeds in ok.
6. Tighten the nut back, keeping an eye on the sensor, do it by hand first as you lift the sensor.
6.a. Not too tight, snapping it off is probably going to be trouble.
7. Test by pumping up the primer and looking for seepage.
7a. If it still leaks use more PTFE and make sure you get it wrapped properly at the start.
HTH
P.S. When I did mine I let it sit overnight so it was cold (and some fuel had drained back to the tank) so there was no fuel everywhere when I did it.
