This place rocks! The OP asked for a part#,but gets a slew of opinions about replacing the pick-up. As far as the pick-up I would try Mancini..see if they can help,they list a few on their site,maybe one would work for ya?
Now,my opinion. If in doubt replace it! $30.00 bucks is cheap insurance if you ask me. I have also seen a few pretzeled pump drives.The screen is NOT fine enough to stop debris big enough to lock up a pump! the pump is the ONLY piece lubed with unfiltered oil!!
