Tim, it's because the Teflon tape can shear off small flakes of the
Teflon,
and get clogged up in the carb, fuel injection, selector valves, etc.

Theoretically, you're supposed to skip the first thread or two when you
wrap threads with Teflon tape. If you do this, the tape won't ever come
into contact with the fluid (gas, in this case).

Why take the chance on installing something that could cause a problem if
you don't install it correctly? You probably could land your airplane with
one eye closed, but not many people are interested in increasing their risk
level...

Also, even if you install it correctly the first time, one day that drain
will clog again, you'll pull it out and replace it with a new one. Can you
be absolutely sure you're not going to leave any of the used tape stuck
inside the female fitting where the drain attaches? If you do leave a scrap
of tape in there, the new fitting will push those tape shards back into the
fuel tank, which is exactly where you don't want it.
