P0456 Gas cap issue

Hey guys,

I recently got the P0456 - Evaporative Emissions System - Small leak detected

I have been troubleshooting for a while in trying to figure this out without going to the shop because I like to do the work myself and save $$.

Before hand, I visually inspected the hoses all the way to underneath the fender well.

Whats interesting about this situation is I replaced the gas cap(oem) but at random times the gas cap missing light will come on in the dash but but would go off a minute later without me tampering with it. This happens every 2 weeks or so.

This is the only thing stopping me from passing inspection which, at this point is way past due.

Have yall experienced this before? I would really appreciate y'alls input.
