Complete add on fuel filter kit specifically designed to fit under the hood on 2001 thru present Dmax equipped pickups. The 2006 and later trucks will need the stainless air box tray. The 2015 will need some trimming in the area beneath the air box tray. This unit can be plumbed either before or after the OE unit, but I prefer after. This kit comes with all of the necessary hoses, fittings, and a two filter elements.

"It has been proven by numerous revisions of the OEM filter that fuel quality and filtration levels are not up to the task of protecting your fuel system. Running this dirty fuel through our Duramax engines has caused many premature injection system failures. Secondary fuel filtration ensures that we will give these components the best chance for a long, and healthy life!" - JK
"Always carry a spare filter for both the factory, and the auxilliary unit at all times, and use a quality emulsifying conditioner like FPPF Total Power at every fill-up. Check out the Filtermag as a great addition to your improved filtration!" - JK
