Description
xOverview
Upgrade your LS swap EFI with the EVIL ENERGY kit that combines a precise 58 psi fuel regulator and a high‑flow external pump. The system is designed to deliver clean fuel and stable pressure, supporting reliable startup and steady performance across a range of driving conditions.
Precise fuel control for LS engines
At the heart of the setup is a regulator calibrated to maintain a steady 58 psi. Paired with an integrated 10‑micron filter, this configuration helps keep fuel entering the injectors clean and consistent, which can contribute to smoother idle and more predictable throttle response in daily driving and spirited sessions alike.
High‑flow pump for modern EFI demands
The external pump delivers up to 300 LPH at 13.5V, supporting higher horsepower builds. It is engineered to perform under pressure (up to 75 psi) and to operate reliably across a wide temperature span from -68°F to 194°F, making the kit suitable for varied climates and uses.
Wide compatibility and installation flexibility
Designed for 1999–2014 Chevy V8 LS‑series engines (4.8L, 5.3L, 6.0L) with 12V DC EFI systems and capable with gasoline or diesel fuels. The regulator is ideal for engine‑bay mounting to stabilize pressure, while the pump is intended for below‑tank mounting to leverage gravity where possible. The kit also includes mounting hardware and adapters for a cleaner, more streamlined install.

Real‑world use and benefits
Enthusiasts often find that a dedicated regulator and high‑flow pump help maintain stable fuel delivery during varied driving scenarios, support EFI upgrades, and keep wiring and connections organized with a complete hardware set. While actual gains depend on the full drivetrain and tuning, this kit offers a practical upgrade path for LS‑based builds.
