EVIL ENERGY External Inline Fuel Pump for 12V EFI — 300 LPH, 75 PSI Rated, Plug-and-Play Kit

EVIL ENERGY's external inline fuel pump delivers up to 300 LPH for 12V EFI systems, offering high flow, wide temperature tolerance, and plug-and-play hardware for faster installations.

This compact inline pump is built for fuel-injected engines that need reliable delivery under demanding conditions. Designed specifically for 12V DC EFI setups, it balances high flow rates with straightforward mounting and includes adapters and electrical terminals so you can fit it into a variety of fuel lines without hunting for extra parts.

How much flow and pressure can this pump provide?

The pump is rated to produce 300 LPH when tested at 43 PSI and 13.5 V, with additional factory test figures at lower voltages. It’s also rated to operate up to 75 PSI, making it suitable for most EFI fuel rails and returnless systems that require a steady, high-volume feed.

• 300 LPH at 43 PSI and 13.5 V (factory test)
• 255 LPH at 43 PSI and 12 V
• 200 LPH at 75 PSI and 12 V
• Rated operating pressure up to 75 PSI

What fuels and temperatures does the pump handle?

This unit accepts a range of common fuels used in street and race applications, and it’s engineered to tolerate extreme ambient and operating temperatures. That makes it suitable for seasonal use, performance tuning, and motorsport support where heat resilience matters.

• Compatible with gasoline, pump gas, race gas, and diesel
• Operating temperature range from -68°F to 194°F
• Materials selected to resist common fuel blends

How easy is installation and what hardware is included?

The pump ships with a full set of mounting and connection hardware so you can install it quickly—recommended below the tank to preserve gravity-fed fuel flow. A detailed manual is included to guide routing, electrical hookup, and sealing to reduce leaks and electrical issues.

• Mounting bracket, gaskets, washer, and nuts included
• 10AN inlet adapter and 6AN outlet adapter for common fuel lines
• Two insulated electrical terminals and rubber connection covers
• Installation manual with recommended below-tank placement

Will this pump suit my EFI car or project build?

It’s designed specifically for vehicles using 12V EFI systems that require a robust external pump rather than in-tank units. If your engine demands high flow for upgrades, forced-induction tuning, or larger injectors, this pump gives the capacity and connectors you need without adding complicated plumbing.

• Engineered for 12V DC EFI applications only
• Ideal for high-flow street, track, or race conversions
• Recommended for setups where external mounting below the tank is feasible

Who is this for: Experienced DIY installers, professional tuners, and enthusiasts upgrading fuel delivery on 12V EFI engines will appreciate the EVIL ENERGY external inline pump. It’s best for builds that need higher flow than stock in-tank pumps can deliver, drivers who run varied fuel types, and anyone who wants a compact, hardware-complete replacement or supplement to their existing fuel system.
