Not today, but a couple weeks ago - swapped fuel tank out on my '93 SE-R.
Started leaking slightly when full awhile back, gradually got worse until after a fill-up, had a 3-4 foot puddle in garage next morning.
211k miles, driven in WI winters did it in.
Was leaking from the seam on the front passenger side corner of the tank.
Didn't drive it for a couple months until I found the time to swap it out for a used non-leaking tank. Cleaned up the rust on used tank, painted with rust converter, followed by a couple coats of high temp black.
The swap is not the most fun job to do, but not too bad.
Glad to be driving it again!
Now I have to fix the '98 SE - flex pipe trashed, very loud...
