EFI Fuel System Plumbing Kit

The EFI Fuel System Plumbing Kit by Holley is a comprehensive solution designed for automotive builders transitioning to electronic fuel injection or upgrading from carbureted systems. This kit is ideal for those retrofitting classic engines, building street rods, or modernizing race vehicles, providing all necessary components without the hassle of sourcing them individually.

Engineered for reliability and precision, this plumbing kit ensures optimal fuel delivery pressure and flow characteristics essential for EFI performance. It includes pre-assembled and individual hard-line and soft-line components made to OEM specifications, featuring durable braided stainless steel construction for enhanced corrosion resistance. The fittings are sized to match fuel pump output and injector demand, minimizing pressure drop across the fuel rail.

This plumbing kit is particularly beneficial for LS engine swaps and both small-block and big-block builds, making it a versatile choice for any platform moving from mechanical fuel delivery to Holley's EFI system. Installation is straightforward for builders with basic mechanical skills, though professional installation is recommended to ensure optimal performance.
