Fuel Pump Module Assembly (FG1224) by Delphi®. With External Strainer. Delphi fuel assemblies are designed to deliver an immediate, uninterrupted flow of fuel to the engine’s fuel rail and injectors at the specified system pressure, resulting in more efficient operation. Additionally, where required, fuel assemblies include integrated fuel level sensing components that deliver an accurate reading of the fuel level in the tank to the fuel gauge and ECM/PCM. Fuel modules and hanger/senders typically include a fuel vapor pressure sensor that detects any leaks in the fuel tank or associated evaporative emissions components.
