I'd add this to the list of all time stupid dealer stories but for the fact that it has happened before but not often and not twice to the same person. Take home message don't go to the dealer for any basic stuff like filters, batteries, wiper blades, unless you are in tight with the parts manager and can get a good price on the right parts.
As to the gas filter the Mopar # is 52129238AA and it doesn't take a genus to find it in the KJ parts fiche where it's listed as "filter, fuel" immediately after "FILTER, Fuel/Water Separator". I'm partial to WIX although NAPA Gold is the same thing with a different paint job and the same basic parts #. Oil filter WIX filters-oil 51515 (7 qts oil) vs 51516 (stock 6.3 qts oil); I like the oversize one and it's an even fill amount. WIX fuel 33647; air filter 42329; transmission filter set 58843. The WIX fuel filter runs ca. $28 from Amazon with free shipping.
As to the filter head. If you have the one with the blue plug on the drivers side (heater element and it's almost the same size as the other plug) then you have the 2n gen filter head which is good. It wasn't a recall item but probably should have been. FYI going price for the combined 2n gen filter head with a filter on it and a WIF sensor in the filter and the wiring is ca. $125.
I'd suggest you post the extra filter head for sale in case someone needs one.
If you have not already done so read Sir Sam's NOOB guide and keep in mind the timing belt job that must be done no later than 100,000 miles.
