A quid says the screech is a dry EXUP valve. It'll sound like it's coming from under the tank (which strictly speaking it is ... ) it's just a bit lower than your ears are telling you.
Strip, clean, copper grease, reinstall and set the cable slack - job done.
Fuel pumps click.
EXUP servo motors whirr and sometimes crackle but never heard one screech.
I think my quid is safe.
