The PureFlow AirDog Raptor 4G provides a dedicated, frame-mounted fuel supply designed to keep fuel moving consistently toward the injection system. Rather than overcomplicating the truck with unnecessary plumbing, the Raptor 4G is engineered around the factory fuel system and gives you two flow options to match your build.\u003c\/p\u003e\n\u003cp\u003eThe Raptor 4G mounts to the frame jig in front of the fuel tank for a clean, application-specific installation. The suction line connects to the factory suction fitting on top of the fuel module, while the pressure side connects directly to the factory injection-pump feed line on the frame. Its internally regulated design eliminates the need for a separate return line, keeping the installation clean and reducing unnecessary fuel-system plumbing.\u003c\/p\u003e\n\u003ch2\u003eWhich Flow Rate should you choose?\u003c\/h2\u003e\n\u003cp\u003eWhen it comes to upgrading your fuel system, choosing the right GPH (gallons per hour) rating isn’t about picking the biggest number; it’s about matching your pump to your truck’s real-world demands.
