Getting error code 454
 

I have a 2003 Mitsubishi Eclipse GTS with a rippmodds supercharger. I have been getting the usual codes:
300-Random Misfire
172-Bank 1 to rich
175-Bank 2 to rich
But today I got code:
455-EVAP Emission Control System Leak (Large)
Should I be worried about that

Nevermind figured it out the plastic 90 degree elbow coming off the side of gas tank is leaking. This causes the tank not to build pressure causing this code
