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
- Requires the WAP109 5/8-inch suction tube and 5/8-inch suction hose, with fuel-tank access for installation unless a suitable sump is used.
- Uses a frame-standoff/cradle-bracket installation in front of the fuel tank.
- Air/vapor return connects to the modified fuel module; retain the original engine return.
- 2011-2014 and 2015-2016 kits use different wiring-harness applications. Order by the vehicle year, not just the shared LML engine designation.
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.
Installation reference
