P1456 DIY applying Permatex gasket sealant on fuel filler neck tube on a 2000 Honda Odyssey EX

The link below is a status update.    • Update on P1456 code check engine light on...   My 2000 Honda Odyssey kept getting check engine light with P1456 code related to fuel vapor leakage. I replaced the gas cap, 2 way valve, and vent valve but those didn't fix my p1456 problem. In this video I attempted to apply Permatex gasket sealant on the fuel filler neck to prevent any fuel vapor leakage.
