Edelbrock’s Universal EFI Sump kit is also designed to provide the necessary high-pressure fuel required for EFI applications in vehicles still using a mechanical fuel pump. This is a complete self-contained system that can be easily installed under the hood.
How does an electronic fuel injection system work?
In its simplest terms, an electronic fuel injection (EFI) system is a computer controlled fuel delivery system. This electronic control unit (ECU) reads various sensors located on the vehicle and makes the determination of how much fuel to allow the engine to have based on this information.
