The AirDog FP-100 and FP-150 Fuel Lift Pumps are designed to deliver consistent fuel pressure and remove air, vapor, and debris from diesel fuel before it reaches your engine. By providing a steady, clean fuel supply, these pumps improve throttle response, extend injector life, and boost overall performance for Cummins, Duramax, and Powerstroke trucks. Owners often notice smoother acceleration, better fuel economy, and more reliable towing power with an AirDog lift pump installed. If your truck is experiencing hard starts, hesitation under load, or fluctuating fuel pressure, it may be time to replace your factory system with a high-quality upgrade like the FP-100 or FP-150. These pumps are built to handle the demands of daily driving, heavy hauling, and performance tuning alike.
The AirDog II-4G and II-5G Series Fuel Lift Pumps represent the next generation of PureFlow technology, built for truck owners who demand maximum efficiency and reliability. These systems not only maintain consistent fuel pressure but also feature advanced motor designs that reduce noise, improve durability, and increase overall flow capacity. Perfect for tuned or heavily worked diesel trucks, the II-4G and II-5G pumps support higher horsepower applications while still delivering the clean, steady fuel supply AirDog is known for. If you’re pushing your Cummins, Duramax, or Powerstroke to the next level, these pumps make sure your engine keeps up without starving for fuel.
The Raptor RP-4G Series Fuel Pump is another solid choice for truck owners who need dependable performance without unnecessary complexity. Known for its quiet operation and easy installation, the RP-4G provides consistent pressure to keep your engine running smoothly, whether you’re towing, hauling, or daily driving. If your factory pump is struggling to keep up or you’re noticing power loss under load, upgrading to a Raptor RP-4G is a cost-effective way to protect your injectors and restore your truck’s performance.
