Part Number: AP63722
Manufacturer: Alliant Power



Fuel Injection Line For 2001-2004.5 Chevy 6.6L LB7 Durmax Engines (Lines 4 & 5) 6.6 L LB7 Duramax Injection Lines are prone to corrosion build up due to their through the valve cover design. When lines are removed during service, existing protocol requires cleaning the lines or replacing with new.

With cleaning comes inherent risks such as damaging the mating surface of the line that seals to the injector as well as introducing damaging particles into the injector which can lead to failure. Alliant Power now offers these lines at a cost effective price point when compared to labor intensive and potentially damaging cleaning procedures as well as expensive lines through the OEM. Manufacturing Process: -Manufactured using industry leading processes ensuring strength to extremely high pressures -Line and nuts are coated with a specialized chemical treatment to extend corrosion resistance -Manufactured to the Highest Quality Standards Using Industry Leading Technology -Cost Effective Replacement Alternative to OEM Lines and Risky Cleaning Procedures Validation Testing: -Lines withstand intense pressure pulsation and burst testing over 36,000 psi (13,000 psi more than the application will ever see) Cleanliness: -Attempting to clean lines for re-use damages the sealing surface that mates to the injector inlet and can lead to leaks causing fuel in oil (dilution) -Residual particles from cleaning can enter and damage the injector
