Hey there, fellow truck enthusiasts! If you're looking to give your diesel rig a serious boost in performance, let me introduce you to the aFe Power DFS780 Fuel System. This isn't just any fuel system; it's designed specifically for GM diesel trucks from 2017 to 2019, including the Chevy Silverado 2500 and 3500, as well as the GMC Sierra. Trust me, this thing is built to handle the demands of your heavy-duty workhorse.

One of the standout features is the built-in bypass for the stock fuel system. Under light loads, your vehicle can run on the stock fuel pump, which is pretty handy for those everyday drives. And if you're like me and love to keep an eye on things, the clear high-impact polycarbonate sight glass lets you visually inspect your fuel. No more guessing games here!

Now let’s talk about the guts of this system. It’s equipped with helical bronze spur gears that are more forgiving of contaminants than their steel counterparts. Plus, they run quieter, so you can enjoy your ride without the annoying whine of straight cut gears. And speaking of durability, the billet 6061-T6 aluminum manifold eliminates any concerns about porosity that you might find with cast aluminum. This thing is built to last.

The marine-grade motor is another game-changer. It's protected against dust and powerful water jets, so you can take your truck off-road without worrying about the elements messing things up. Installation? A breeze. The plug & play system comes with a harness that connects directly to the battery using Deutsch weather-proof connectors—no cutting or modifying stock fuel lines. If you ever want to return your truck to stock, you can do it in no time.

What’s really cool is the boost-activated pump engagement. The supplied preset boost switch activates the pump only when you need it, reducing wear and tear on the DFS780 pump. And for those who like to keep track of their setup, there’s a fuel pressure gauge port (1/8" NPT) for easy monitoring. You can really keep tabs on what's going on under the hood.

Let’s not forget about the PEEK bearing wear surfaces that help reduce noise and wear on the spur gears. Plus, the contoured CNC machining of manifold passages enhances flow, which means less pressure drop and better performance overall. With a flow rating of 187 GPH at 8-10 psi, this system is ready to keep your engine fed and happy.

Oh, and the O.E. quality Viton seals are compatible with both diesel and biodiesel fuels, so you have some flexibility there. Just a heads up—this system isn’t CARB exempt, so if you're in California, you might want to look elsewhere.

Overall, if you’re looking to upgrade your fuel system and enhance your truck's performance, the aFe Power DFS780 is a solid choice. Typical install time is around 2 hours, so you’ll be back on the road in no time. Built right here in the U.S.A., this system is ready to tackle whatever you throw at it.
