Did you shut the valve off? I forgot and left mine on once.
If it is off and still leaking out the tube in the front of the motor.. Then you will need oring replacements.

Did you get your filter at Napa, or somewhere else that private labels Wix filters? If your new filter didn't come with a beveled gasket, then you need to coat the almost flat gasket with engine oil to prevent it from leaking.
Also make sure the rubber gasket from the old filter did not come off the bottom of the filter and stay in the fuel bowl. Two gaskets in the bottom will prevent you from being able to tighten down the lid properly.

I would have to agree with the others, Lid/gasket not seated right.
Or what i have seen in the past:
The filter drain lever. Just below that there is a rubber hose about an 1" long. It attaches to the metal tube that runs down the front of the motor and to the back of the water drain valve. I have seen were someone had plugged the metal tube down below. (probably cause it leaked) and it blew off the rubber hose on top.(which has no clamps on it) All because the o rings in the water drain were shot.

When the truck is running or when the key is on? If it is when the truck is running it would seem to be after the fuel bowl. If when the key is on the fuel pump is keeping the fuel pressurized.

Your fuel bowl only has pressure when the truck is running, so it wont leak much while off. I am betting on Orings, or a cracked water drain assembly (not the bowl, but the little plastic handle assembly). After you repair, spray some simple green on the engine and then rinse with a LOW PRESSURE garden hose. Do not fire up the pressure washer and think you will get it cleaner, faster. You will end up getting water in sensor plugs and have a bigger headache than a fuel leak.
PS dont get the simple green on your paint, it will strip the wax off and can dull your finish.
