CP4 Fuel Pump Fallout: Silverado Sierra Owners Demand Justice in Swirling Lawsuit Storm In recent months, the Chevron Performance Fuels CP4 fuel pump has become the center of a mounting crisis among Silverado and Sierra truck owners across the U.S. What began as consumer concerns over performance and reliability has spiraled into a full-blown legal and reputational storm, with hundreds of drivers filing lawsuits against both fuel providers and vehicle manufacturers. Dubbed the “CP4 Fuel Pump Fallout,” this developing case highlights critical issues of product safety, corporate accountability, and the growing frustration among owners demanding justice. ## The Rise of the CP4 Fuel Pump Controversy The CP4 fuel pump, originally engineered by Chevron Performance Fuels for enhanced engine performance in heavy-duty applications, is now at the heart of a controversial debate.
