Fuel Injector Connector Set for GM Duramax Applications

If you’ve been chasing down injector trouble codes on your L5P Duramax—especially anything from P0201 through P0208—it might not be the injector itself causing the problem. A failing connector is often the real culprit, and the Fleece Replacement Fuel Injector Connector 8-Pack is the go-to solution to fix it right the first time. Whether you're swapping injectors or just cleaning up an aging harness, these plug-and-play connectors offer a reliable and permanent fix to one of the most common electrical headaches on 2011–2024 Duramax trucks. Fleece includes a full set of eight injector connectors, each with a 4.5-inch pigtail, so you have everything you need to refresh the entire set at once. No need to worry about matching random wire gauges or inconsistent crimps—the wires are machine cut and precision-crimped in-house using fully automated processes, so you're getting the same consistency and reliability you’d expect from a factory harness. That kind of attention to detail matters when you’re dealing with components this close to the heart of your engine.

Straightforward Install

Installation is straightforward. Each connector comes with heat-sealable butt-style connectors, making the job clean, simple, and secure. If you're already in the engine bay replacing injectors, this is the ideal time to take care of worn or brittle plugs before they cause hard-to-trace drivability issues down the road. Plus, replacing them now helps eliminate resistance-related failures, which are often the root cause of those frustrating injector codes that come and go.
