However water in the fuel has nothing to do with the emissions related problems that they are in court over...and I dont understand why its just the 2500's as the 3500's have the same system.

What I read was the trucks are not meeting the emission requirements and either the 3500 has a different emissions requirement or it was an over sight which I would guess it to be the latter.

Perhaps Shiner can comment on this as I don't really follow the emissions requirements.
