2019 Ram 1500 Classic

[huberdoo]

I have 2019 Ram 1500 classic 3.6 gas engine. gas tank won't fill without continuous shutting off pump and overflowing. I have check engine light and evap system light is on. I have had everone of the valves replaced as well as a new module that operates them.
Still have the same problem. any ideas?

Clogged charcoal canister, filter maybe. Do you always stop filling at first click or do you sometimes click the handle 1-2 more times to squeeze more in? Do a search here, lots of discussion on this topic.

Did you have the steep gas filler neck replaced with the updated part? I believe that was still a problem with the 2019 classic, but it was common on 2015 to 2018. Mine clicked off constantly, and the filler neck would get stuck in the truck as well. There are other issues as well, but that was a main one. Do not top off, or it can cause a problem.

However mine never overflowed, so yours might be a clogged evap canister.
