EVIL ENERGY 300 LPH External Inline Fuel Pump 12V — Black, 60mm Bracket, EFI-Compatible

EVIL ENERGY's 300 LPH external inline fuel pump is a compact 12V EFI-compatible pump that delivers up to 300 liters per hour with a 60mm mounting bracket for reliable aftermarket fuel delivery.

This inline fuel pump is built for engines with electronic fuel injection systems that need a robust, compact pump capable of handling gasoline and diesel blends. Rated for continuous operation across a wide temperature span and supplied with a full hardware kit, it’s intended to replace or upgrade factory pumps in performance and retrofit applications. The pump’s performance is measured at different voltages and pressures so you can match it to your vehicle’s fuel system requirements.

How much flow and pressure does this pump provide?

The EVIL ENERGY pump produces measured flow rates depending on voltage and backpressure: about 200 LPH at 75 PSI and 12V, 255 LPH at 43 PSI and 12V, and up to 300 LPH at 43 PSI and 13.5V. Its maximum rated operating pressure is 75 PSI, which suits many EFI setups that require higher feed pressure than a stock pump.

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

What fuels and conditions is the pump compatible with?

This pump is compatible with gasoline variants and diesel, including pump gas and race fuels, making it versatile for street and track. It’s engineered to work across extreme temperatures, from deep cold to very hot environments, and is specified for 12V DC EFI systems only.

• Accepts gasoline, pump gas, race fuel, and diesel
• Designed for 12V DC EFI systems
• Operating temperature range: -68°F to 194°F

How is the pump installed and what comes in the box?

The pump is intended to be mounted below the fuel tank to allow gravity-assisted feeding, which helps maintain steady inlet flow. EVIL ENERGY supplies a complete installation kit with adapters, mounting hardware, and clear instructions to simplify fitment and plumbing for most engines.

• Includes 60mm mounting bracket and rubber covers for connections
• Comes with 10AN inlet and 6AN outlet adapters
• Supplied hardware: gaskets, washer, nuts, insulated terminals, and manual

What electrical and sizing considerations should I check before buying?

Confirm your vehicle has a 12V DC EFI system and that your wiring and fuse rating match the pump’s current draw at the voltage you expect to run. Note the pump’s flow varies with voltage and system backpressure; sizing should consider peak engine demand and any added fuel pressure regulators.

• Must be used with 12V DC EFI systems only
• Flow changes with voltage and system pressure—verify against engine needs
• Install below tank for optimal inlet feeding and longevity

Who is this for: EVIL ENERGY’s external inline 300 LPH pump fits car enthusiasts, tuners, and mechanics who need a compact, high-flow replacement or upgrade pump for EFI systems. It’s suited for street builds, race-prep projects, and diesel applications that require a durable pump with a full hardware kit and clear installation guidance. If you need reliable flow up to 300 LPH, broad fuel compatibility, and simple below-tank mounting, this pump offers an affordable, ready-to-install option.
