CarBole Universal 12V Inline Fuel Pump – 300 LPH High Flow with Mounting Bracket

Overview

The CarBole Universal Electric External Inline Fuel Pump provides a versatile, externally mounted solution for EFI engines. It runs on DC 12V and is compatible with both diesel and gasoline configurations. For longevity, avoid fuels with alcohol or E85 and pair the pump with a pre-filter to protect the pump and fuel system.

Performance and compatibility

This pump is designed to deliver strong flow for modern EFI setups while remaining compact and serviceable. Typical flow is tested across pressures to support a range of tuning goals. In practice, you can expect solid performance at common EFI operating points, with the flexibility to support higher horsepower applications when paired with the appropriate lines and filters.

• Test flow around 200 LPH at 75 PSI
• Approximately 255 LPH at 43 PSI
• Max up to 300 LPH at 43 PSI and 13.5 V
• DC 12V operation for wide vehicle compatibility

Each unit is 100% brand new and designed as a universal external inline pump. It does not require mounting inside the fuel tank, offering installation flexibility for many EFI configurations.

What’s included

• Pump unit
• Mounting bracket
• Inlet adapter
• Outlet adapter
• One way check valve
• Two gaskets
• Two nuts
• Two terminals
• Two covers

Installation and placement guidance

For reliable operation, the pump is recommended to be installed below the fuel tank to allow gravity fed flow from the tank. When mounted on a vehicle, the external inline design supports stable startup and compatibility with many turbocharging setups, while simplifying service and replacement compared to an internal, tank-mounted pump.

This pump offers flexible placement options and straightforward wiring, making it suitable for EFI upgrades, fuel system refreshes, or replaces a factory inline pump in compatible engines.

Practical benefits and cautions

• External mounting reduces complexity and can ease maintenance
• High flow potential supports higher performance applications
• Universal applicability to diesel and gasoline EFI systems
• Use with a pre-filter to help protect the pump and fuel system

Note that the unit is not intended for fuels containing alcohol or E85. Always follow proper wiring polarity and consult vehicle-specific guidelines when integrating with turbocharged or high-power builds.
