Walker Fuel Injector Connector Pigtail 06-10 GM 6.6L Duramax LLY/LBZ/LMM

Is your truck misfiring, running rough, or throwing injector circuit codes because of a bad connection? The Walker Fuel Injector Connector Pigtail is the fix for one of the most common and overlooked issues in your fuel system: a damaged or failing injector connector. Over time, factory plugs become brittle, clips break, and wiring degrades, leading to poor injector communication and inconsistent fuel delivery. This Walker pigtail restores a clean, secure connection between your injector and wiring harness, allowing your engine to run smoothly again with proper fueling, improved idle quality, and reliable performance whether you're daily driving or working your truck hard. Built for durability in harsh engine-bay conditions, the Walker pigtail is manufactured from high-quality materials that withstand heat, vibration, and long-term use. It includes the mating connector, butt connectors, and heat shrink, allowing you to create a secure, weather-tight repair that eliminates intermittent electrical issues. Engineered and tested to meet OE specifications, it matches factory fit, form, and function while delivering consistent electrical performance and long-lasting reliability in demanding diesel applications.
