Installation overview

- The suction side hooks up to the factory suction fitting in the fuel module.
- The pressure side connects directly into the side of the P-Pump bypassing the factory fuel filter housing, and factory fuel pump.
- The injection pump return is tied into the engine return to eliminate the need for the factory filter head.
- The AirDog Air/Vapor return is sent back to the tank through a filler neck tee.
Tech tips
- Choose flow capacity around the complete fuel system and intended use; a GPH rating is not a guaranteed horsepower or fuel-economy gain.
- Use the exact kit's installation instructions for hose routing, electrical connections, priming, leak checks and operating-pressure verification.
- Confirm tank, pickup and filtration modifications before scheduling installation. The overview above does not replace the installation manual.
