EVIL ENERGY Electric Intank/External Fuel Pump High Flow Kit Fit for 12V DC EFI system

The EVIL ENERGY 300LPH fuel pump is an external fuel pump for compatible 12V DC EFI systems. This 12V inline fuel pump has published test points of 300 LPH at 43 PSI and 13.5V, 255 LPH at 43 PSI and 12V, and 200 LPH at 75 PSI and 12V. Maximum operating pressure is listed at 75 PSI.

For a 50–60 PSI inline fuel pump requirement, compare the published flow at the intended pressure and the voltage available at the running pump. Do not estimate engine support from the 300LPH name alone. Wiring, filtration, hose restriction, regulator setup, and fuel type can all reduce delivered flow.

External Fuel Pump Setup

• Mount close to the tank and at or below the tank outlet when a safe gravity-fed layout is possible.
• Use a suitable coarse pre-filter and fine post-filter according to the complete EFI design.
• Protect the pump from exhaust heat, drivetrain movement, road debris, and direct impact.
• Use an appropriately sized relay, fuse, power wire, and ground.
• Confirm inlet and outlet threads, included fittings, mounting space, and fuel compatibility before ordering.

Searches for an EVIL ENERGY 044 fuel pump may refer to an external pump style rather than a guaranteed interchangeable model. Verify the actual dimensions, connection threads, electrical requirements, and published flow instead of relying on the “044” name alone.

The 255LPH in-tank electric fuel pump is intended for compatible 12V EFI systems requiring an in-tank pump motor rather than an external pump. Published flow is 255 LPH at 43 PSI and 12V and 190 LPH at 80 PSI and 12V, with a listed operating range of 15–90 PSI.

This is a pump motor kit, not a complete fuel-pump module. It does not include an integrated fuel-pressure regulator. Confirm the pump dimensions, outlet size, electrical connector, strainer position, module housing, and fuel compatibility before installation.

• Suitable for compatible gasoline and approved ethanol-blend applications stated for the selected variant.
• Do not use with diesel unless the exact variant documentation explicitly permits it.
• Verify fuel pressure, loaded voltage, wiring capacity, and regulator requirements.
• Inspect and clean the tank before installing a new pump and strainer.

The EVIL ENERGY 110LPH fuel pump is a replacement-style in-tank pump motor for selected 12V applications. Published output is at least 110 LPH at approximately 43.5 PSI and 12V, with current draw listed at no more than 7.0A.

OE references include E8335, E8212, E8229, E8254, E8213, and E2068. Selected application references include Honda Civic, CR-V, Element, Fit, and Insight; Toyota 4Runner, Avalon, and Celica; Mazda Miata and MPV; and Lexus IS, GS, RX, and ES models. Model name alone is not enough to confirm fitment.

• Match the OE number whenever possible.
• Confirm model year, engine, pump dimensions, outlet, strainer orientation, and electrical connector.
• Confirm whether the original vehicle uses a separate regulator or a complete module assembly.
• The package is a pump motor kit and does not replace every component in the original module.

• Disconnect the battery and relieve fuel-system pressure before opening the system.
• Work in a ventilated area away from sparks, flames, hot surfaces, and ignition sources.
• If the vehicle must be raised, support it securely with jack stands; never work under a vehicle supported only by a jack.
• Confirm pump polarity, relay, fuse, wire size, ground quality, and voltage at the running pump.
• Use fuel-compatible hose, seals, filters, and fittings rated for the selected fuel and operating pressure.
• Prime the system, verify pressure, and inspect every connection for leaks before starting or loading the engine.

Q: What is the difference between the external and in-tank fuel pump options?
A: The 300LPH pump mounts outside the tank in a gravity-fed EFI layout. The 255LPH and 110LPH pumps install inside a compatible fuel-pump module or hanger.

Q: Which option is the highest-flow pump?
A: The 300LPH external pump has the highest nominal rating, but selection must be based on flow at the intended pressure and voltage.

Q: Does the 255LPH pump include a built-in regulator?
A: No. It is an in-tank pump motor kit and requires the vehicle or custom system to provide compatible pressure regulation.

Q: Is the 110LPH pump a complete fuel-pump module?
A: No. It is a replacement-style pump motor kit. The original module housing, level sender, regulator, or other application-specific parts may still be required.

Q: Can the external pump be used as a 50–60 PSI inline fuel pump?
A: It may be suitable when its published flow at the target pressure meets the system demand. Verify loaded voltage, regulator setup, filtration, and fuel type.

Q: Are these fuel pumps compatible with E85 or diesel?
A: Compatibility varies by pump variant and every wetted component in the system. Confirm the exact pump, hose, seals, filter, and regulator before use.

Q: Why should an external fuel pump be mounted below the tank?
A: A gravity-fed inlet reduces suction restriction and helps limit cavitation and fuel starvation.

Q: How is fitment confirmed for the 110LPH pump?
A: Match the OE number, model year, engine, module design, dimensions, outlet, strainer position, and electrical connector.

Q: What electrical parts may still be required?
A: A suitable relay, fuse, wiring, ground, connector, and vehicle-specific installation hardware may be required depending on the selected pump.

Q: Is professional installation recommended?
A: Professional installation is recommended when fuel-system design, tank removal, module modification, wiring, or pressure testing is outside the installer’s experience.
