Fiat and Cummins in court

I went to home depot and bought a 1.5'' plumbing test plug...(kinda like a boat plug has a wingnut to tighten and seal) the 1st day I brought my Ram home. Just for a sense of security. There are 2 flaps in the fuel fill neck, and I personally see no way of water getting in the tank...not to the point of big issues


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.
