Fitment and ordering notes

• Application range: 2011-2014 GM 6.6L Duramax. Confirm the engine and existing fuel-system configuration before ordering.
• This listing is limited to 2011-2014; a shared LML engine code does not make the adjacent-year kit interchangeable.

Installation overview

• Mounts to the frame jig in front of the fuel tank for the application-specific installation.
• The suction side hooks up to the factory suction fitting in the fuel module.
• The pressure side connects directly to the factory injection pump feed line on the frame.
• The AirDog Air/Vapor return is sent back to the tank through a filler neck tee.
• Uses the factory fuel-module suction fitting; this manual does not call for a draw straw.
• The tank connection uses the FQC118S 11.8 mm connector, identified by a red dot and 11.8 marking. Do not substitute the similar FQC12S fitting.
• Kit hardware includes the pump/filter assembly, mounting hardware, wiring harness, fuel hose, quick-connect fittings and filler-neck return hardware.
• Keep the original engine fuel-return circuit connected.

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.
