D13 Fuel Problem (HEAD SCRATCHER) UPDATE

UPDATE Finally figured it out. Someone was kind enought to put out a cigar in the fuel tank at some point at my wits end pulled off every single fuel line off the engine and found tobacco leave in the line between the ecm cooler and the fuel filter housing. just took it for a test drive and no more issues everything is perfect. If you are having fuel problems and you have separator mounted on the bottom its worth it to check all the lines. people are ####ty and they put all kinds of #### in the tanks when noone is looking. Just cost this guy #### near $6000 in repairs to the fuel system cuz someone was being an A S S

 

this one doesn't have it at least not the new ones.

 

well whatever the case is had it or not i could not cut the tank to see it, but the fact is that somehow this #### get in the fuel line make it past ecm cooler and got stuck in line. truck is running like hell now pulling and everything with no issues
