well after digen in , i found something very interesting . some fords have this module in the back of the speedo cluster that is called a slosh module ford ((

))) do the super dutys have these ? the problem i am having is when the tank is full and reads correct as it slowly goes down to empty and the warning light comes to refill . after i fill her up and turn the key the gauge just goes to 1/4, then very very slowly goes to half tank after about 15 mins of driveing. next day it still on half tank but an hour of driveing it goes to 3/4. then about a half hr it finley's get to full. if these trucks have a slosh model is it behind the speedo cluster or some where else
Thank you for any help
