today truck died bout two days ago fuel filter light was coming on and off NOT water in fuel light. I noticed it cutting out once in awhile felt like it was defueling you could say. this light indicates fuel pressure/restriction also. so of course I replace the fuel filter nothing and I come to notice the fuel bowl is not refilling itself as I turned the truck over. I tried to manually prime the fuel bowl and crank it some more it would just suck that fuel down. before it completely died It was real low power and and would start to cut out and almolst stall til I got it off the road after it set it would start and idle rough but wouldn't drive without stalling. not sure if my mechanical cam driven fuel pump went out or ipr screen is clogged or ipr just completely **** the bed. or it could just be just sucking air somewhere, also have heard of problems similar with the valve for switching tanks going bad any suggestions helps cant fool with it til after work tomorrow thanks
