Fiat and Cummins in court

OK I just tried it again today to make sure and nope not one drop of fuel on the ground even though the filler tube was full between the first and second flaps!

So if fuel can't leak out than water nor dirt can. So again this is why I have a cap to protect the fuel system in my truck. A simple latch would hold the fuel door close and keep water and dirt from getting into the fuel filling area.

The Ram is the only FCA vehicle that I know of that does not have a cap to protect the filler tube from getting any contaminates in it.
