# Fleece Performance 17-22 GM 2500/3500 Duramax L5O Replacement Fuel Injector Connector

A common failure point on the L5P Duramax, our replacement connector with 4.5" pigtail for the fuel injectors will get you back on the road quickly. This connector is typically replaced during an injector replacement and is prone to increased resistance over time that can result in an injector DTC (P0201-P0208). Includes two heat-sealable butt-style connectors. Replaces GM: 19368140
