Not an AD but an SB from Lycoming. Text:

"New, rebuilt and overhauled engines shipped from Lycoming between
Oct 1, 2001 and Feb 2, 2004 with fuel pump P/N LW-15473..."

You can read the rest at the link provided earlier and decide if
you wish to comply at this time.

And decide at what point this may become an AD.

Yep. A mandatory service bulletin is designed to do two things...

1) Get the word out that there is or may be a problem.

2) Reduce Lycoming's liability.
