Same thinking that Darkness, although plastic connectors are used on later Ducati’s (1198, 848, etc), one half of the connector is fitted to the tank, with less flex than with both sides on the fuel line. I went the metal way for those and although I can’t find the details at this very moment, I am pretty sure they are from a German motorsport supplier. Fuel line routing was also changed slightly and a support made to clamp the connector along the frame. May be an overkill but it has been on the bike for 2 years with now problems.
