The DFD-4000 screws on in place of the stock filter. Per FASS, that gets rid of the time and cost of changing the stock filter every 5-10K miles, lets fuel flow without the restriction, and gives you a gauge port to watch fuel pressure.\u003c\/p\u003e\u003cp\u003eFASS lists it for 2001-2016 GMC\/Chevrolet. FASS is also clear that this has to be used with another form of fuel filtration, like a Titanium FASS system. Don't run it on a truck with only factory filtration.
