Fleece Performance Fuel Pressure Sensor

Fleece Performance Fuel Pressure Sensors: Diesel-Grade Precision

When your diesel truck's fuel system is throwing codes or acting up, the integrity of every electrical connection matters. Fleece Performance Engineering has built its reputation as one of the diesel aftermarket's most trusted names, and that same engineering discipline carries directly into their line of fuel pressure sensors and related sensor connector products.

Why fuel pressure sensing matters: The fuel rail pressure sensor is a critical input for your truck's ECM, continuously reporting high-pressure fuel system data that governs injection timing, fueling quantity, and overall engine health. In some cases, the factory fuel rail pressure sensor connector can become loose or corroded , leading to erratic engine behavior, misfires, or a check-engine light that's difficult to diagnose. Fleece's sensor products are designed to address exactly these failure points with properly engineered, drop-in replacements.

What Fleece Performance Offers in This Category

Fleece's fuel pressure sensor lineup focuses on diesel applications across the three major domestic platforms — Cummins, Duramax, and Power Stroke. Their products include sensor pigtails, replacement connectors, and complete wiring harness solutions tailored to each engine family.

• Rail Pressure Sensor Pigtails: Designed to connect your Duramax or Cummins rail pressure sensor, these pigtails ensure a proper electrical connection for accurate fuel system monitoring, covering applications such as 2003–2012 5.9/6.7L Cummins, 2001–2016 6.6L Duramax, and 2014–2015 Chevrolet Cruze.
• Fuel Pressure Regulator & Multiuse Pigtail (FPE-HAR-FPR-PT): This versatile pigtail fits various 2003–2018 RAM Cummins sensors and switches, as well as 2001–2016 GM 6.6L Duramax injection pump, fuel temperature, DEF pump, and fuel injector applications — plus Ford 6.7L Power Stroke and Nissan Titan HD Cummins fitments.
• Fuel Pressure Regulator Wiring Harness: The FPR Wiring Harness for 2001–2010 6.6L Duramax provides a complete harness solution for the injection pump's fuel pressure regulator circuit.
• 0–300 PSI Pressure Sensor with Pigtail: The FPE-PS300G-KIT is a gauge-style 0–300 PSI pressure sensor supplied with an electrical pigtail , suitable for fuel system monitoring builds requiring standalone sensor gauging.

Built to Fleece's Manufacturing Standards

Fleece's sensor connectors are produced in-house at Fleece Performance, and their manufacturing process includes fully automated wire cutting and terminal crimping to ensure the highest quality replacement parts. This level of in-house control is what separates Fleece from generic connector suppliers — every pigtail and harness is built to the same tolerances as their high-end performance components.

Fleece Performance holds ISO 9001:2015 Certification , reflecting a formal commitment to quality management across their entire product range, including these precision electrical components. Whether you're chasing a fuel system fault code or building a clean, reliable diesel, Fleece's sensor products give you the confidence of a purpose-built, diesel-specialist solution.
