OSIAS External Inline EFI Fuel Pump 380LH, 12V, AN10 IN/AN6 OUT, 60mm Bracket

Overview

The OSIAS External Inline Fuel Pump is engineered for 12V DC EFI systems, delivering dependable fuel delivery in a compact inline package. Placed between the fuel tank and the engine, it supports a gravity-assisted flow setup when mounted below the tank, contributing to a smoother and more consistent supply under varying driving conditions.

Real-world performance and use scenarios

Performance can vary with pressure and voltage, so the pump offers flexible flow across common EFI configurations. At 75 PSI and 12V, you may see around 200 LPH. Reducing pressure to 43 PSI with 12V can yield roughly 255 LPH. If you run 43 PSI with 13.5V, the flow can reach about 380 LPH. These figures reflect typical EFI system demands and wiring choices, helping you gauge if this pump aligns with your build.

Consider OSIAS for tasks like upgrading a street or light track car, or for a project that requires reliable fuel delivery during throttle transitions and varying engine demands. The goal is a steady supply rather than a guaranteed outcome, so plan for your specific setup and conditions.

Key advantages

• Broad fuel compatibility including gasoline, pump gas, race gas, diesel, E85, and alcohol blends
• High-flow versatility across different pressures and voltages to suit EFI needs
• Wide operating temperature range suitable for diverse climates
• AN10 inlet and AN6 outlet fittings for flexible plumbing options
• 60 mm bracket clamp included for secure mounting

Installation tips and best practices

• Install the pump below the fuel tank to leverage gravity-assisted flow for smoother operation
• Follow the included instructions to ensure proper wiring and system compatibility with a 12V supply
• Verify your vehicle’s fuel system configuration and required flow before integrating the pump

Notes on usage and maintenance

While the pump supports a wide range of fuels, operate within the specified compatibility conditions and electrical supply to maintain stable performance. Regular checks of fittings, fittings, and connections help ensure continued reliability in EFI applications.
