Ducati switched to this type of quick-disconnect when the 749/999 came out and has continued to use them on all models with quick disconnects. There is no aftermarket product available. The OEM fittings work fine so long as they are used properly. If the outer band on your quick-disconnect has cracked the entire disconnect needs to be replaced. To prevent future breaks NEVER try to squeeze the outer ring to remove the disconnect in cold temperatures (below 50 degrees F). The plastic becomes brittle in colder temperatures and will crack. The fitting comes with the two orings on the shaft. Lube the o-rings prior to inserting them into the fuel pump flange.
