2011-2016 LML Duramax Low Pressure Line Conversion - CP3 Swap Upgrade Kit - by UnderDog Diesel

This kit is a part of our CP3 Conversion kit, and we are offering it as an upgrade option to those running other CP3 Conversions!

This kit is not required if you currently are running the following kits, as they include something similar,

• UnderDog Diesel (UDD)
• Screamin Diesel Performance (SDP)
• John C Garage (JCG) 

Our kit includes 

• 36" Gates 1/2" Fuel Hose
• 5" Gates 5/16" Fuel Hose
• 3 or 4 Hose Worm Gear Hose Clamps (depending on model year)
• 2 Fuel Injection Style Hose Clamps
• Quick Connect 90 Degree Fitting (12-16 MY only)
• Billet Quick Connect Coupler (12-16 MY only)
• Billet Wye Fitting

This kit removes the factory low pressure line connection in the valley that is prone to leaking after an install, as it uses a flare connection and may not be properly reseated, and all around, can be a headache to fix.

Our kit puts the low pressure line routing outside of the bottom of the valley, allowing for easy access if necessary and offers a clean routing to run fuel supply directly to a CP3 (if running an aftermarket lift pump with filters).
