Default Got a code PO456

This is what it is --> Evaporative Emissions System - Small leak detected

Causes:

A small leak in any of the EVAP hoses or fuel tank hoses
A small leak in the purge valve or vent valve
The EVAP Canister may be leaking
Gas cap not sealing

Does anybody have an online manual or something showing me where the above items are? I don't have a clue how to tackle this issue

I have a 2005 V6 5 speed 80k miles on it.

Thanks!!

Yeah first thing I checked, it is on fine but I have no idea if it is leaking, is there a way to test it?

I was going to mention that 9 times out of 10 it's the gas cap...
