The entire fuel filter housing is covered with fuel residue. How do you know the leak is in the wire connector area? The more probable cause would be at the fuel line connections or possibly the O-ring on the filter canister having some slight seepage.
The first thing I would do is clean the housing completely with something like electrokleen or brakekleen and then watch it closely to see where the source of leak/seepage is at & then go from there. By the look of things, the dealership didn't clean the housing before they condemned it, this might be something as simple as an O-ring replacement.
