Description
2001-Early 2004 GM/Chevrolet 6.6l Duramax LB7 Dorman OE FIX Flexible Stainless Steel Braided Fuel Line 819-801
The Dorman OE FIX Fuel Line 819-801 is a premium replacement rear fuel line engineered to address one of the most common fuel system failures found on 2001-2004 GM heavy-duty trucks. Factory steel fuel lines are susceptible to corrosion at the fittings, eventually causing leaks, fuel delivery issues, and costly repairs. Dorman's OE FIX design improves upon the original equipment by replacing the rigid steel sections with flexible PTFE tubing wrapped in braided stainless steel and finished with corrosion-resistant stainless steel fittings for superior durability and service life.
Unlike conventional replacement fuel lines, the 819-801 is manufactured to the exact length and configuration required for a direct installation, eliminating the need to bend or fabricate replacement tubing. The flexible braided construction also simplifies installation in tight areas while providing excellent resistance to vibration, road debris, chemicals, and corrosion. Designed as a direct-fit replacement, this fuel line restores dependable fuel delivery while helping prevent future corrosion-related failures.
