Resolved: "Tighten Gas Cap" code

Hi, all!

Consistently getting a "small leak in EVAP system" and/or "Tighten gas cap" codes.

I tightened gas cap, checked it out (no wear or rot or nicks in seal). Cleaned it a few times. No changes

After some research, I replaced the Vapor Leak Detection Pump. Still getting the codes.

What should be my next place to look?

Thanks for any advice

2015 Ram 1500 V6, 60k miles.

Update: changed the vapor leak pump, it took a couple of days before the light stopped coming on. Apparently that was it.
