OEM Ducati Fuel Pump Part # 430.4.004.1A  This fits many many models.
 
No Chinese Junk here! There is no shortage of online sellers marking up Chinese pumps, putting thier names on them.  You know what I am talking about. A $29-Chinese  knock off with a "Lifetime" Guaruntee, being sold for $45-$100.   Believe me, you will regret it.  Immediately, on the side of the road, or with a dead bike next season.  There are kits out there asking you to modify the wiring, instructions on how to drill relief holes, use the fuel sock that looks nothing like what you have.   All red flags.  
 
Google it, "re-sellers mark-up artists"  have attached OEM Ducati part numbers to Chinese pumps.   Fairly certain there is a reason Ducati doesnt use them.  
 
Don't forget to add your new filter, screen,  fuel lines and to upgrade your quick disconnects.
