Will this fit a 2011 freightliner m2 -106 bus with 6.7 Cummins?

I am not sure but I didn’t know if it would fit my truck and it fit perfectly it should it just pushes in there it doesn’t twist on or anything but the def one twitch twists on a little bit I figured for 10 or 12 bucks how can you go wrong I love it I love opening up my fuel door in seeing it

How tight is the diesel cap?

All I can say is tight enough to work good. In my opinion fits perfect.

Will this fit a 2021 ram 1500 ecodiesel?

Don't know about 2021 ram, but is fits my 2019 perfect.

Will these work on 2021 Cummins?

Men worked on 2018 Ram 3500, don’t know why they wouldn’t work on 2021.
