I almost learned the hard way that my CARB compliant fuel cans would not work with my new truck that has a capless fuel tank. While I have used these cans with my old truck (2017 Ram 1500), my new truck (2022 Ram 1500) has a capless fuel tank. When I tried to pour the fuel into my tank it went everywhere but into the tank. Seems the capless tank has two fuel flaps. The one you can see and one further down the filler neck. The nozzle does not penetrate far enough to open this second flap. There I was driving around in the middle of nowhere secure in the fact that I had ten extra gallons of fuel “just in case” when in reality I had no way to get that fuel into my tank if needed. It could have been a very serious situation. Just some FYI for everyone to consider since capless seems to be the way of the future.
