EVIL ENERGY EFI 255LPH In-Tank Fuel Pump Kit – High Flow 43 PSI for 12V EFI Systems

Overview

The EVIL ENERGY EFI 255LPH In-Tank Fuel Pump Kit is built for 12V DC EFI systems that run on gasoline. It is designed to deliver fuel with a steady, regulated flow, helping your EFI setup maintain consistent performance across varying driving conditions. The pump’s in-tank design aims to keep fuel delivery efficient while reducing heat transfer to the fuel.

Core specifications at a glance

Engineered to perform under a range of pressures, the pump delivers a tested flow of up to 255 LPH at 43 PSI and about 190 LPH at 80 PSI. The system operates within a 15–90 PSI window, with the final fuel pressure set by the regulator. This flexibility supports different engine demands while keeping fuel delivery stable.

• Application: fits 12V DC EFI systems only.
• Performance: 255 LPH at 43 PSI; 190 LPH at 80 PSI; operating range 15–90 PSI; final pressure set by regulator.
• Fuel type: gasoline only; designed for stable and efficient delivery. High-impurity fuel may affect lifespan and performance.
• Installation notes: pump diameter may differ from the original model, but functionality remains; hoses, filters, or other components may need replacement; professional installation is highly recommended.

Real-world use and benefits

In everyday driving and light-to-moderate tuning scenarios, this high-flow in-tank pump can help maintain a steady fuel supply during throttle changes and assist the EFI system in keeping consistent pressure as engine demand shifts. The compact in-tank form fits many OEM layouts, potentially supporting smoother operation without intrusive exterior hardware.

• In-tank design can help reduce heat exposure and preserve fuel quality near the pump.
• Higher flow capability may contribute to more stable idle, smoother throttle response, and steadier acceleration in compatible setups.

Notes for best results: while diameter differences from stock are possible, they do not impact overall use for the intended EFI setup. Ensure hoses and filters are compatible with the new pump, and consider professional installation to confirm wiring, mounting, and regulator setup are correct.

Why consider EVIL ENERGY

This kit emphasizes reliability and flow consistency, with a focus on providing a robust, gasoline-only solution for 12V EFI systems. The information reflects tested flow ranges and operating conditions, and it presents a practical, user-focused view of what you might experience under real driving conditions. It is a possibility-based improvement, not a guarantee, and results depend on your specific engine, regulator configuration, and fuel quality.
