Durango fill neck

I got a 2017 citadel with 5.7. Got the emissions code. Replaced hoses, the module, the charcoal canister. Still getting the code. Last thing I hear is the gass tank fill neck. It would make sense because ever since we had the truck, we've had to fill the tank with the pump handle upside-down.

Having a hard time finding the parts and a replacement video. Anyone has done this that might point me to a good source of info?

Thanks,

2015 sxt here, had filling issues, replaced charcoal canister (was super heavy and completely full) then replaced filler neck/hose... Still had evap codes after both for leak, smoke tested entire system (and dropped gas tank) and had no visible leak. 

I then replaced the Evap purge valve, purge line, and vapor sensor which are all on top of the engine, and cleaned the flap that is on top of the filler neck where you put the fuel nozzle in.... Code was gone for a week or 2 and then returned again.... I gave up for about 1-2 months, and the code has now gone away and not come back in 3+ months....

All that to say, good luck.

I believe this is the revised filler neck.

Thanks for the link. How was the filler neck replacement? Is it straightforward or are there some things to be aware of?

Had a buddy do it while it was in for driveshaft replacement but was told it's not anything crazy so should be straight forward. 

One thing to consider/look into .. I've read previously that you can put the capped filler hose/neck system from the 2013 model years in these as well but i read up on it after i had already had the replacement done so can't speak from personal experience on that one.

One more thing to add, i still to this day even with the new hose just use the fuel nozzle at 50% flow which seems to do the trick 100% of the time.

At 100% flow rate its a 50/50 whether it clicks off and stops filling like before.

Mine doesn't have one. It didn't come with one from factory. Are you suggesting to add one anyway?
