EVIL ENERGY EFI Fuel System Kit — 300LPH External Pump, 10‑Micron Inline Filter, Adjustable 20–120 PSI Regulator (Universal Gasoli

EVIL ENERGY's all-in-one EFI fuel kit pairs a 300LPH external pump with a 10-micron inline filter and a 20–120 PSI adjustable regulator to deliver clean, controllable fuel flow for most gasoline-powered vehicles.

This universal fuel system kit brings together the pump, high-precision filter, adjustable regulator and a comprehensive fitting set so you can upgrade or replace fuel delivery components without hunting for extra parts. Designed for gasoline applications (not diesel or high-alcohol blends like E85), the kit focuses on stable supply, engine protection and on-vehicle tunability via an accessible pressure gauge and changeable springs.

How does this kit improve fuel delivery under heavy load?

The 300LPH external pump supplies high-flow capacity while the adjustable regulator maintains consistent pressure across operating conditions. Together they reduce the risk of fuel starvation during sustained high RPM or boost conditions, helping deliver reliable fuel to the injectors.

• 300 liters-per-hour external pump for high-demand situations
• Adjustable regulator (20–120 PSI) to tune pressure for various setups
• Precise 10-micron filtration minimizes particulate entry to the fuel rail
• Includes gauge and replacement spring for quick pressure verification and range changes

What filtration protection does the 10-micron inline filter provide?

The inline filter uses a multi-layer media to capture fine contaminants down to 10 microns, preventing debris from reaching pumps and injectors. This filtration level balances flow capacity with effective particle removal suitable for most gasoline EFI systems.

• Multi-layer element traps dust and metal particles
• 10-micron rating reduces injector wear without overly restricting flow
• Replaceable element design for straightforward maintenance
• Fittings included to integrate the filter into common fuel line sizes

How easy is installation and tuning with the included fittings?

The kit ships with a broad assortment of AN and ORB adapters, a pressure gauge and mounting brackets so you can fit it to most vehicles without extra purchases. Basic mechanical skills and standard tools are sufficient; use sealing tape on regulator threads and follow the supplied recommendations when replacing springs or setting target pressure.

• Comprehensive fitting kit: 6AN, 10AN, ORB adapters and common metric fittings
• Brackets and hardware included for pump and regulator mounting
• Gauge (0–160 PSI) for on-vehicle pressure confirmation
• Replacement spring (75–120 PSI) to extend regulator range

Are there any fuel compatibility or safety notes?

The EVIL ENERGY kit is intended for gasoline EFI systems and is not compatible with diesel or high-alcohol fuels such as E85. During installation, ensure all fittings are sealed properly and observe safe handling practices for gasoline. Adjust regulator pressure gradually and verify with the included gauge.

• Not for diesel, E85 or alcohol-based fuels
• Use sealing tape on regulator gauge interface as recommended
• Adjust top screw and/or swap springs to reach desired pressure
• Verify pressure under operating conditions before finalizing installation

Who is this for: The EVIL ENERGY 300LPH EFI fuel kit is suited for mechanics, tuners and DIY enthusiasts updating fuel delivery on gasoline performance builds, street cars and many OEM conversions. It’s ideal when you need higher flow capacity, improved particulate protection and a tunable, on-vehicle pressure solution without sourcing multiple adapters and components separately.
