Lawn Racing Fuel Rail Mod Kit (2018–2020 F-150 5.0L)

Eliminate the Factory Fuel Rail Restriction

The Lawn Racing Fuel Rail Mod Kit is designed to address a major fueling restriction found on 2018–2020 Ford F-150 5.0L Coyote platforms. From the factory, the fuel rail utilizes a small internal crossover passage to supply the port injection system from the high-pressure pump inlet. While adequate for stock power levels, this restrictive design quickly becomes a bottleneck on boosted and high-horsepower applications.

Designed for High Horsepower & Boosted Builds

Under increased load, the factory crossover can restrict fuel flow to the port injectors, potentially leading to lean conditions, inconsistent fueling, and reduced performance. The Lawn Racing Fuel Rail Mod Kit solves this issue by adding a high-flow external crossover line that bypasses the restrictive OEM internal passage entirely.

Consistent Fuel Delivery When You Need It Most

By improving fuel volume and consistency to the port injectors, this system helps support the demands of supercharged, turbocharged, and E85-powered setups. Whether you're building a street truck or a dedicated performance application, this upgrade ensures your fuel system can keep up.

Premium Components & Clean Installation

The kit includes high-quality fittings and a durable braided crossover line for long-term reliability and a clean engine bay appearance. Designed for straightforward installation, it integrates seamlessly with both stock and aftermarket fuel systems.
