The 6" Duramax Fuel Pressure Regulator Pigtail Harness is a compact and dependable wiring solution designed to interface with Bosch-style fuel pressure regulators used on L5P Duramax diesel engines. Engineered for precise fitment, this harness features a 2-way Bosch connector with blue keying, ensuring accurate alignment and electrical connection to late-model GM fuel pressure systems. The harness simplifies installation by offering a direct plug-in to the regulator, while the opposite end is a blunt-cut pigtail, allowing easy splicing into your vehicle’s factory or custom wiring harness.
With a 6-inch lead length, this pigtail is ideal for tight engine bays and confined spaces. It’s well-suited for fuel system diagnostics, pressure regulator replacements, or harness repairs on modern Duramax platforms—helping to restore proper fuel delivery control and maintain consistent engine performance.
