Guzzi used the teardrop gastanks on the California models from the late 1990's until well into the 2000's. On the fuel injected bikes, at some point they changed from an external fuel pump to the internal version. As best I can tell this was about 2003. Can anyone verify? My Son is looking for a tank to fit his Stone, I believe it has the external fuel pump. He needs to know what year-models ha has to choose from.
Thanks, & a happy thanksgiving to all y'all
