Description

The AirDog PureFlow II-4G DF-100-4G Fuel Pump is a top-grade fuel system upgrade designed to maximize your vehicle's fuel system efficiency, enhance engine performance, and increase fuel economy and torque output. This patented Fuel Preporator by AirDog removes various large contaminants that could damage or jam the gerotor fuel pump. The entrained air/water vapor is separated and then discharged through the positive fuel air separation features. The air/vapor enters the return port after the regulator, allowing pure fuel to flow to the engine at a regulated positive pressure. This system also removes fuel not needed by the engine, allowing it to flow through the regulator and return to the fuel tank. The AirDog II-4G features a single-piece pump body, replacing the old 3-piece design, which reduces the number of parts, unit size, and weight, resulting in a sleek, low-profile pump assembly and eliminating the need for leaky, messy gaskets. No drilling is required for installation. Note: This product is NOT legal for installation on vehicles required to meet CARB standards and/or registered in California and other states following CARB standards, including NY and ME.
