Hello all, another nwb here. I have recenlty starting having a problem with my 04 6.0. Shortly after my Low Fuel Light comes on the truck shuts down as if it is out of fuel, I used to get another 50+ miles afterward. It used to be my daily driver until a year ago but now it sits all week and I use it on the weekends. Do I have water (due to moisture buildup) in my tank or does this sound like a sending unit/fuel pickup problem. I have run several tanks with monster diesel additive to see if it was a bad fuel thing but still have the problem. Any ideas?
