Just one quarter of the full tank leaking, now it has been settled at 3/4 tank after, no leaks.

Did you recently do a DIY LPFP upgrade? I was chasing the same problem after reusing the seal, don't drive like this because it drips on the exhaust and could burn your car down. Take off the right side rear seat cover, unscrew the hatch (10mm bolts), and it will be very obvious if it is leaking. Get a new seal, make sure the bucket is seated properly and the locking ring is properly torqued, and drive up some hills to see if it continues to leak.

Any little static charge in the system somewhere can spark a fire too. I wouldnt drive it

I had a leak after I did a DIY lpfp, turned out to be a wire getting pinched in the seal. But if you didn't do that then I'd imagine it would just be one of those two seals on top of the tank.
