Q: What is an inline fuel pump?
A: An inline fuel pump is an external 12V Electric Fuel Pump that sits along the fuel line, outside the fuel tank. Unlike in-tank units, an external fuel pump is easier to install, service, and replace, making it the preferred choice for a high-flow fuel pump for EFI system in performance builds and custom fuel delivery projects.
Q: Is the EVIL ENERGY 300LPH fuel pump universal?
A: Yes. This is a Universal Fuel Pump designed for most vehicles with a 12V Fuel Pump requirement and a 12V DC EFI system. As a Universal Inline Fuel Pump, it provides flexible compatibility for various makes and models, though specific fitting requirements may vary by vehicle.
Q: What types of fuel can this 300LPH Fuel Pump handle?
A: The EVIL ENERGY Fuel Pump is highly versatile and engineered for diverse mediums. It is fully compatible with gasoline, pump gas, and race gas, and serves as a reliable Inline fuel pump for E85, ethanol, and alcohol. Additionally, its robust alloy steel construction makes it a dependable diesel inline pump for diesel-based applications.
Q: How much fuel flow does this high-flow fuel pump for EFI system provide?
A: This 300LPH Fuel Pump is a powerhouse, delivering 300 liters per hour at 43 PSI & 13.5V. With a maximum operating pressure of 75 PSI, it ensures consistent fuel delivery for high-performance engines, as noted in many an Evil Energy fuel pump review.
Q: How should I perform an External fuel pump installation?
A: For the best performance, mount the pump below the fuel tank to ensure a gravity-fed supply. Every kit includes clear evil energy fuel pump installation instructions for guidance. A proper External fuel pump installation prevents cavitation and ensures your Universal Inline Fuel Pump maintains peak efficiency.
Q: Do I need additional fittings like a 10AN Fitting or 6AN Fitting?
A: Most users will not need extra adapters. This 300LPH Fuel Pump includes a 10AN Fitting (M181.5) and a 6AN Fitting (M121.5). Choosing the 10AN Fitting with Pump or 6AN Fitting with Pump configurations provides a secure, leak-proof connection for your 12V Electric Fuel Pump.
Q: Is this 12V Fuel Pump noisy compared to in-tank pumps?
A: While external pumps are generally louder than in-tank models, the EVIL ENERGY Fuel Pump is engineered to minimize vibration. Professional Evil Energy fuel pump review feedback suggests using rubber isolators during External fuel pump installation to further dampen sound and protect the Universal Fuel Pump.
Q: Does the Universal Inline Fuel Pump require a fuel filter?
A: Yes. It is strongly recommended to use a high-quality fuel filter (100-micron pre-filter) before the pump. This protects the 12V Electric Fuel Pump from contaminants. Using a proper filter ensures the longevity of your high-flow fuel pump for EFI system and maintains clean fuel flow.
Q: What warranty does EVIL ENERGY provide for the fuel pump?
A: This EVIL ENERGY Fuel Pump comes with a 6-month warranty. If you experience issues during normal use, our customer support is ready to help. Our 180-day return policy and dedicated warranty further reinforce the quality standards seen in every Evil Energy fuel pump review.
Q: What is the current draw for this 12V Electric Fuel Pump, and do I need a relay?
A: The EVIL ENERGY Fuel Pump typically draws around 10-13 Amps at 43 PSI. To ensure your 12V Fuel Pump operates safely, we strongly recommend using a 30A or 40A relay and 10-12 gauge wiring. This professional-grade power setup is essential for any High flow fuel pump for EFI system to prevent voltage drops and protect the longevity of your Universal Fuel Pump.
Q: How does the Universal Inline Fuel Pump handle vapor lock or overheating?
A: Thanks to its high-quality alloy steel body and precision internals, this 300LPH Fuel Pump is designed for efficient heat dissipation. If you experience performance drops, check your External fuel pump installation. As noted in many an Evil Energy fuel pump review, ensuring the Universal Inline Fuel Pump is shielded from exhaust heat will prevent vapor lock, especially when used as an Inline fuel pump for E85.
Q: Is the EVIL ENERGY Fuel Pump compatible with pulse width modulation (PWM)?
A: Most users run this 12V Electric Fuel Pump at a constant 12V-13.5V for maximum reliability. While it is a robust Universal Inline Fuel Pump, it is best suited for traditional relay-triggered systems. If you are using a PWM controller, ensure it is rated for the high current of a 300LPH Fuel Pump to maintain the High flow fuel pump for EFI system stability found in our official Evil Energy Fuel Pump installation instructions.
