AirDog Boost Compensation Kit For 4G & 5G Lift Pumps

Boost your performance with the AirDog Boost Compensation Kit for 4G & 5G Lift Pumps. Designed with the needs of high-horsepower diesel builds in mind, this kit ensures steady, full fuel pressure under extreme loads, all with just a single pump. Whether you’re pushing for more power or aiming to extend your fuel system’s life, this upgrade has you covered. Here’s how it works, the kit redirects boost air from your engine’s compressed air side into the adjustable diaphragm fuel pressure regulator. For every pound of boost air sent, an additional pound of fuel pressure is added to the system. This means no more pressure drops during wide-open throttle, keeping your injection system performing at its peak. The included adjustable air pressure regulator allows fine-tuning (0–50psi), ensuring your fuel system operates efficiently whether cruising or under heavy acceleration. It’s perfect for balancing high flow and longevity, maintaining lower fuel pressure during idle and cruising but ramping it up when you hit the throttle. Upgrade your AirDog 2 5G or Raptor 4G lift pump with this kit and take your fuel system to the next level.
