In-tank fuel pump 255 L/hr, ø 39.5 mm – up to 450 PS

High-Performance In-Tank Fuel Pump 255 l/h (E85-compatible) – up to 450 PS

Compact high-flow fuel pump for direct installation in the fuel tank. With a flow rate of 255 liters per hour at 3 bar system pressure, the in-tank pump ensures a stable fuel supply for performance-tuned engines. It effectively prevents a drop in fuel pressure under full load, thereby avoiding harmful lean-burn effects and thermal damage to pistons and valves.

Thanks to its slim design, the upgrade system is ideal as a replacement for aged or overloaded stock pumps. The internal components are specifically designed for continuous operation with E85 ethanol.

Technical Specifications

Key Product Features

• Stable Fuel Pressure: Guarantees precise fuel metering via the fuel injectors, even at high boost pressures.
• Compact plug-and-play design: The 39-mm housing diameter fits into most stock surge tanks and mounts.
• E85 Compatibility: Robust materials protect the pump mechanism from corrosion caused by alcohol-based fuels.
• Ready-to-install package contents: Includes a matching wiring connector, intake strainer (fuel filter), and rubber insulation.

Important Fit Note

To ensure optimal alignment of the intake filter, compare the design and positioning of the intake opening on your original fuel delivery unit with our product images before placing your order.

Electrical Installation Instructions

Due to its higher flow rate, the motorsport pump requires more operating current than a stock pump. Check the wire gauge of the original power supply. If the stock wires are thin, it is recommended to connect the pump via a relay with a fused direct connection to the battery to ensure full flow rate and prevent overloading the vehicle’s wiring harness.
