These are the codes im getting

455 evaporative emission control EVAP system large leak
457 loose fuel cap -----------This is not true the cap is new
420 catalyst system efficiency below threshold Cylinder bank 1

There maybe a vacuum hose issue ' not a fuel line issue 'but im not sure what this vacuum line is called, the line is on the driver side on the left side of the tank 'plastic quick connect dry rotted and broke ..i need to know what this line is called in order 'to order it

What is the exact location of the part. Is it part of the vapor canister is it part of the purge valve or are you talking about the gas tank.  You have to be detailed  other wise it will be really difficult to help you out.

Is this the part your looking for.  I assume your talking about the line that runs from fuel tank to vapor canister 


Yes the line looks something like that '' it has a quick connect fit on the end and it does run from the tank to the front of the vehicle , im not sure where it connects to up front , but it does run from the tank to the front ' and look just like this one

I disconnected the battery and the Gas cap display went out on my dash ' but im still hearing that annoying buzzing sound and not really sure where to pin point its sound location

That goes from gas tank to the canister . Buzzing noise? You said you can't pin point it's location but what general location is it coming from.  I noticed that alot of parts are discontinued .  I can't find any direct fit lines . You may have to go to dodge and speak to parts department of you want to replace that line . I don't think it's available and you have to use a vacuum line or a reinforced rubber hose. I'm trying to pull it up on all data and a few other sites but I'm having issues with my login again
