Fiat and Cummins in court

I note that the article mentions moisture. I find it interesting that they don't/didn't on a 2016 or 15 use a gas/diesel cap on the fuel "port". have some funky rubber gasket like thing on the fuel door and once water gets past that it has free entry into the fuel tank.

It's an interesting system when you see how it works. Water doesn't actually have free entry into the fuel tank. The gasket on the door is only one part (and doesn't do much).

There are two hinged doors on the fuel inlet itself - one at the very top, and one several inches down. In between is a part that will allow water to drain out if it makes it past the upper hinged door.

That's why the diesel nozzle has to be fully inserted. If the lower hinged door isn't open, nothing gets to the tank.

Many folks find they are buying one of the billet aluminum caps that are available, but many don't and have no issues.
