Have a 2017+ L5p Duramax
with fuel injector concerns?
This specific make and model can pop injector codes at relatively low mileage due to how the engine heat is dispersed near the fuel injector pigtail harnesses from the factory. To remedy this issue Fleece Performance makes aftermarket pigtails for the injectors that eliminate the issue. We now stock them on the shelf and have saved customers significant costs by correctly diagnosing and installing these upgraded components as opposed to selling an entire set of fuel injectors that may not always be needing replacement when these fuel system symptoms and codes arise.
