EVIL ENERGY 12V External Inline Fuel Pump 300 LPH — Universal EFI, 75 PSI Max, Compact High-Flow

This compact external inline pump is built for 12V EFI fuel systems that need reliable, high-volume delivery. Engineered to handle gasoline, pump gas, race gas and even diesel, it offers a wide operating temperature range and is supplied with installation hardware and adapters to simplify fitting into many setups. Performance-tested at multiple pressures and voltages, the unit balances strong flow with practical installation considerations for under-vehicle or in-line placement.

How much flow and pressure can I expect from this pump?

Flow varies with system pressure and voltage: the pump has confirmed test results at several common conditions so you can match it to your application. It is rated to operate at a maximum pressure of 75 PSI and a peak tested flow of 300 LPH under higher test voltage.

• 200 LPH at 75 PSI and 12V (test condition)
• 255 LPH at 43 PSI and 12V (test condition)
• 300 LPH at 43 PSI and 13.5V (test condition)
• Maximum operating pressure: 75 PSI

What fuels and temperatures can this pump handle?

The pump is compatible with a range of common fuels, making it suitable for street and motorsport environments where fuel types vary. It also tolerates extreme climates, from very cold starts to high-heat operating conditions.

• Compatible media: gasoline, pump gas, race gas, diesel
• Temperature range: -68°F to 194°F for reliable performance
• Designed specifically for 12V DC EFI systems

How is the EVIL ENERGY inline pump installed and what’s in the box?

Installation is straightforward when following the supplied instructions; best practice is to position the pump below the fuel tank for gravity-fed flow. The pump ships with gaskets, adapters and electrical fittings so you won’t need extra parts for most standard installs.

• Recommended location: install below the fuel tank for gravity feed
• Included hardware: inlet 10AN adapter and outlet 6AN adapter
• Electrical and mounting kit: insulated terminals, nuts, washer, rubber covers
• Documentation: user manual and installation guidance included

Will this pump fit my vehicle’s EFI system?

The pump is designed as a universal external inline unit for 12V EFI systems, but compatibility depends on your vehicle’s flow requirements and plumbing connections. Compare your system’s required LPH and pressure to the pump’s tested outputs and make sure the included AN fittings match or can be adapted to your lines.

• Voltage requirement: 12V DC systems only
• Check: match required LPH and maximum pressure limits
• Adapters: included 10AN inlet and 6AN outlet for common conversions

Who this is for: The EVIL ENERGY External Inline Fuel Pump suits hobbyists, tuners and racers who need a compact, high-flow 12V solution for EFI conversions or aftermarket upgrades. It appeals to anyone wanting a pump that handles multiple fuel types, performs across a wide temperature range, and arrives with the fittings and hardware to begin installation without hunting for additional parts.
