Having fuel pressure issues with your diesel truck? This Fuel Control Actuator (FCA), also called a Fuel Pressure Regulator, is a common replacement part for both GM Duramax and Ford Powerstroke engines. For GM: It fits 2010-2016 Chevy Express/GMC Savana 2500-4500 and 2011-2016 Chevy Silverado HD/GMC Sierra HD trucks with the 6.6L Duramax V8. For Ford: It fits 2011-2019 Ford F-250 through F-550 Super Duty trucks with the 6.7L Powerstroke diesel. It replaces a bunch of common part numbers, including GM 12641035, Bosch 0928400757, Dorman 904-577, and more (see full list). Its job is crucial: it regulates the fuel pressure in the rail, matching it to the engine's boost pressure for optimal combustion. If it fails, you might get codes like P0087 (pressure too low), P0088 (pressure too high), or P0089 (performance issue), leading to poor power, rough running, or hard starts. This aftermarket unit is built to meet OEM standards for easy installation, stable performance, and reliability. If you're troubleshooting fuel system problems on your diesel, this actuator is often a key suspect and a straightforward fix for a trained mechanic.
