Fiat and Cummins in court

Cummins just like any engine manufacture is given the specs from the vehicle manufacture and told "send us a bid to supply an engine capable of meeting these specs.". If FCA/Ram (T&P) sent them the wrong specs it is on them. If Cummins did not build to the specs it is on them. But like Troy said without a whole lot more information no one can point a finger at either one.

As for the cap less fuel systems the first thing I did after buying my truck was to order this from Mopar
