Overview

The EVIL ENERGY External Inline Fuel Pump 300 LPH is designed to support 12V DC EFI systems that demand steady, high-flow fuel delivery. Built for versatility, this pump works across common fuel types and is engineered to perform across a wide temperature range, making it a flexible upgrade for street and light-track setups.

  • 12V DC EFI compatibility for dedicated fuel system tuning
  • Test flow: 200 LPH at 75 PSI and 12V; 255 LPH at 43 PSI and 12V; 300 LPH at 43 PSI and 13.5V
  • Operating pressure: 75 PSI
  • Operating temperature range: -68°F to 194°F (-20°C to 90°C)
  • Media compatibility: gasoline, pump gas, race gas, and diesel

What’s in the box

  • 1 × fuel pump
  • 2 × gaskets
  • 1 × washer
  • 2 × nuts
  • 2 × insulated terminals
  • 1 × inlet 10AN adapter
  • 1 × outlet 6AN adapter
  • 2 × rubber connection covers

Installation and practical use

For best performance, install the pump below the tank to enable gravity-fed flow from the tank toward the pump. Follow the included instructions to connect the 10AN inlet and 6AN outlet adapters, then secure the assembly with the supplied hardware. This setup supports straightforward plumbing in EFI configurations and can accommodate a range of line sizes.

Real-world scenarios

Whether you are upgrading a daily driver or preparing a track-focused build, the 300 LPH unit offers a balance between footprint and flow. The broad temperature tolerance helps maintain fuel delivery across hot days or cooler starts, while the 75 PSI operating pressure provides a stable baseline for EFI tuning. Users may notice smoother response during acceleration and more predictable fuel behavior in demanding driving conditions.
