Drain the water out of the filter. Its on the passenger side of the truck, on the bottom of the sensor you will find a draincock attatched to your WIF sensor. Be careful to not pull your sensor wires out by accident. Just put a old baby food jar under the drain and you will be good to go.
Might be a good idea to replace the fuel filter and transmission spin on just for insurance purposes. Thats what I did after I bought mine, boy did it make a heck of a differance in the shifting of the truck! But always be careful of the sensor wires of that WIF sensor.
