Description
Replace your 2017–2025 Silverado or Sierra HD with this Genuine GM 13516495 Fuel Pressure Sensor, designed specifically for the 6.6L L5P Duramax diesel platform. This OEM sensor monitors fuel pressure in the frame-rail-mounted high-pressure supply line, located before the CP4 injection pump. A failing or inaccurate sensor can lead to hard starts, reduced power, poor fuel economy, or diagnostic trouble codes — making timely replacement essential.
This is the same exact part installed at the GM factory, ensuring perfect fit, correct readings, and long-term reliability. A location diagram will be included in the listing photos for easy identification.
