I have this truck that came in and the customer is complaining about the wif light on, so i changed the fuel filters and drain the water seperator. he returns and says that is came back on, so like on the 6.0s i ordered the fuel header, while installing it i found a lot of gel/water in the lower part of the hfcm, cleaned it all out and replaced the header. drove it about 10 miles and no light, after the customer came and got it drove it 3 miles and the light came on, truck left but is coming back on thurs. have yall seen anything like this, can i get just the sensor or do i need to get the whole pump, have not seen any tsbs or ssms, or did i miss something.
