EVIL ENERGY External Inline Fuel Pump Red 300LPH
The EVIL ENERGY Inline Fuel Pump is designed for 12V DC EFI systems. It provides multiple flow measurements: 200 LPH at 75 PSI and 12V, 255 LPH at 43 PSI and 12V, and 300 LPH at 43 PSI and 13.5 V. Operating pressure is 75 PSI, with a wide temperature range from -68°F to 194°F. It supports gasoline, pump gas, race gas, diesel, E85, and ethanol blends, making it suitable for a variety of EFI configurations.
EVIL ENERGY External Inline Fuel Pump Black 300LPH
This external inline pump targets 12V EFI systems with a max flow up to 300 LPH. It lists the same flow/pressure points and operating range as other EVIL ENERGY inline models, including compatibility with a broad range of fuels. The 60 mm bracket clamp provides flexible mounting options for engine bays with limited space, helping to simplify installation in sports and performance vehicles.
SPBREW External Inline Pump 255 LPH High Flow
SPBREW’s inline pump delivers up to 255 LPH with testing at multiple pressures: 3.9–4.1 PSI (215–255 LPH), 42–43 PSI (160–200 LPH), and 72–72 PSI (130–150 LPH). It operates reliably between -68°F and 194°F, suitable for high-pressure EFI conversions. A key benefit is a leak-free connection that connects directly to rubber hoses without extra fittings, simplifying installation and reducing potential leaks.
CarBole 300LPH External Inline Fuel Pump
CarBole offers a universal 12V external inline pump designed to handle up to 300 LPH, with 10AN inlet and 6AN outlet fittings for straightforward integration into new builds or replacing existing pumps. It’s compatible with both diesel and gasoline but advises caution with alcohol/E85 fuels due to potential life impact. The pump is not intended to be mounted inside a fuel tank, aligning with external mounting strategies for many performance vehicles.
Holley 12-170 100 GPH Inline Electric Pump
Holley’s 12-170 is a well-known inline pump designed for high-output EFI and carbureted setups. It supports high horsepower needs and is compatible with PWM control and E85 flex fuels. The roller vane design provides sustained fuel pressure and volume for up to 900 EFI naturally aspirated or 700 EFI boosted horsepower. Its versatility makes it a strong choice for diverse EFI systems seeking reliable fuel delivery.
Buying Guide: Key Considerations For EFI Fuel Pumps
When selecting an EFI fuel pump, consider flow rate versus engine demand. Higher horsepower builds often require pumps with greater flow at challenging pressures, while stock or mild builds may run reliably on moderate flow. Pump compatibility with your fuel type and ethanol content affects longevity and performance. External inline pumps are typically easier to install in engine bays, while in-tank options may reduce heat exposure and noise but require tank access. Noise, reliability, and ease of installation should be weighed against price and installation space.
- Flow and pressure compatibility: match the pump’s 200–300+ LPH and PSI range to your engine’s needs and regulator settings.
- Fuel compatibility: verify compatibility with gasoline, E85, or ethanol blends to prevent premature wear.
- Mounting and installation: external inline pumps need space and secure mounting; in-tank pumps may reduce noise but require fuel-tank access.
- Electrical considerations: ensure the pump voltage (12V or higher) aligns with your vehicle’s electrical system; consider wiring and fuse sizing.
- Reliability and maintenance: look for pumps with simple fittings, leak-free connections, and proven long-term performance.
For EFI enthusiasts, selecting a pump should also account for ancillary components like filters, pre-filters, and pressure regulators. A well-matched combination helps prevent fuel-starved starts, lean conditions, or pressure drops during high-load operation. In some builds, staging or multiple pumps may be used to maintain consistent fuel delivery across rpm ranges, especially under boost or forced induction.
