Fiat and Cummins in court

I do agree with you though as to DEF getting introduced into the fuel system from a spill. Without a cap if someone was careless or even say the plastic hose had a split in it or poped out of the filler neck DEF could get into the fuel .

Even in that scenerio, DEF would still not get in the fuel tank. If you went out to your truck and poured water into your tank and only opened that first flap, the only thing that would happen is it would seep out of the hole between the two flaps. You would have to insert something long enough (and strong enough) to open the second flap in order to get water in the tank.

If you want to test it out and see, get a fuel can of diesel. Try and get diesel in the tank without using the special funnel needed to open the second flap. Then look under your truck to see all the diesel that is coming out of the weep hole and falling to the ground.
