sometimes i think the designers of these thing get so wrapped up in the designing of these engine they forget some of the very basic rules that govern these engines. but in their defense as well, the epa and govt have a hand in it as well.
Do you run bio diesel? I have been told that it can clog your filter like that. I also had a problem with the dealership I had it in three times for a lack of power all they did was reprogam the computer. It was fine for a while and it would come back. I changed the fuel filter myself and its been fine ever since. I had been running bio before that.
ive never ran bio diesel. i dont think i ever will. but i think i ran into some bad fuel and i have an idea where i got into it. i dont blame the designers of this pickup or engine. i think my issue stemmed from bad fuel and clueless dealership mechanics who couldnt fix it. i still love this pickup. so even through all this bull**** im still a duramax man waytogo
bio-dieseland filters Bio-diesel requies a filter that won't re-act to the vegetable oil. That is what clogs regular diesel filters. The filters for boi-diesel will allow regular diesel, bio-diesel and home-made diesel(recycled vegetable oil)
You may want to consider adding a lift pump system like the FASS. Better filtration, less strain on the injection pump, better fuel delivery to injectors and no more fuel aeration throughout the whole system.
