EVIL ENERGY External Inline Fuel Pump Kit — 300 LPH 12V with 10ft 6AN PTFE Hose & Aluminum Fittings

EVIL ENERGY's External Inline Fuel Pump Kit is a compact, high-flow 12V electric pump package (up to 300 LPH) with a 10ft 6AN PTFE fuel line and aluminum fittings designed to upgrade EFI fuel delivery.

This kit combines a robust external inline fuel pump, a reinforced PTFE 6AN hose, and corrosion-resistant aluminum fittings to provide steady fuel flow for gasoline, diesel, E85 and ethanol blends in 12V EFI systems. Built to handle marine, street, and performance environments, the assembly is rated for high pressure and wide temperature ranges so it performs reliably under varied conditions.

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

The EVIL ENERGY pump delivers variable flow depending on voltage and backpressure: test results show about 200 LPH at 75 PSI (12V), 255 LPH at 43 PSI (12V), and up to 300 LPH at 43 PSI when supplied with 13.5V. The unit is rated to operate safely up to nominal 75 PSI, offering the headroom most EFI set-ups require.

• Tested flows: 200 LPH (75 PSI, 12V), 255 LPH (43 PSI, 12V), 300 LPH (43 PSI, 13.5V)
• Operating pressure: up to 75 PSI nominal
• Designed for continuous 12V DC use; higher voltage increases output

What materials and construction protect the fuel line and fittings?

The included 6AN PTFE fuel hose uses a PTFE inner liner for chemical resistance, wrapped in 304 stainless-steel wire for strength, and finished with a nylon outer braid for abrasion resistance and flexibility. The lightweight aluminum fittings resist corrosion while keeping the kit weight down for easier mounting and routing.

• PTFE inner tube resists fuels and ethanol blends
• 304 stainless-steel wire reinforcement prevents collapse under vacuum
• Nylon outer braid adds abrasion protection and flexible routing
• Aluminum fittings for corrosion resistance and secure sealing

How should I install the pump for best performance and reliability?

For reliable gravity-assisted operation and to reduce cavitation risk, mount the inline pump below the fuel tank and follow the included instructions for secure fittings and routing. Ensure electrical connections are solid, use proper clamps at fittings, and keep the PTFE line away from extreme heat sources.

• Mount pump below tank for gravity feed and reduced suction load
• Follow included fitting torque and hose routing guidelines
• Verify 12V supply and secure electrical connectors to avoid voltage drop
• Avoid direct contact with exhaust or hot engine components

Which fuels and systems is this pump compatible with?

The EVIL ENERGY kit is formulated for modern EFI systems and accepts a range of fuels including gasoline, diesel, E85 and other ethanol blends thanks to the PTFE inner tube and stainless reinforcement. It suits many aftermarket and replacement applications where a 300 LPH-class external pump is needed.

• Compatible with gasoline, diesel, E85 and ethanol blends
• Intended for 12V DC EFI fuel systems (external inline configuration)
• Works for street, race, and marine use cases with proper mounting

Who is this for: This EVIL ENERGY External Inline Fuel Pump Kit is aimed at mechanics, tuners, and DIY enthusiasts upgrading fuel delivery on 12V EFI engines that need higher flow and robust hose/fitting materials. It’s suitable for anyone replacing a weak stock pump, tuning for more power, or installing an external pump where chemical resistance, reliability, and simple installation are priorities.
