Hello everyone, I have a 05 6.0 PSD. The other day I had 1/4 tank of fuel and then all of a sudden the fuel hand drops below "E" and fuel light comes on. About 2 miles later the truck acts like it is running out of fuel. I add 5 gallons to the tank and figured that would be enough to register on the Guage and get me a few more miles to a truck stop. I've changed both filters and filled the tank up but it still will not register on the Guage and the truck still cuts out. Please help.
