REPLACEMENT FUEL INJECTOR CONNECTOR W/PIGTAIL FOR L5P DURAMAX

Replacement Fuel Injector Connector with Pigtail | L5P Duramax

Restore proper injector operation on your L5P Duramax with this direct replacement Fuel Injector Connector and Pigtail from Fleece Performance. Compatible with the 2011–2023 GM Silverado/Sierra equipped with the LML, L5P, and related Duramax engines, this connector provides a clean, reliable electrical connection to your fuel injectors — resolving misfires, rough idle, and injector fault codes caused by damaged or degraded wiring.

Why Injector Connectors Fail

Injector connectors on the Duramax are exposed to constant heat cycling, vibration, and fuel vapor. Over time the plastic housing cracks, terminals corrode, and locking tabs break — causing intermittent or complete loss of injector signal. The result is cylinder misfires, excessive smoke, hard starts, and injector-related DTCs. Replacing the connector and pigtail is a fast, low-cost fix that restores injector communication without replacing the injector itself.
