Please excuse what may be a few stupid questions, but I'm interested in the fuel filtering system.
From what I understand, the Duramax uses a CP-3 injection pump like the 3rd gen CTDs, but the Duramax does not have a lift pump.
Does the CP-3 used on the Duramax have an auxilary integral pump to draw fuel from the tank? If not, I would think the fuel filter on the Duramax would run under a slight vacuum. Is this correct?
Is the filter kit, using the Cat filter, used in series with the stock filter upstream of the stock filter?
