Fuelab PRO Series Extreme Flow In-Line Variable Speed Brushless Fuel Pump, 5 GPM Spur Gear

Fuelab PRO Series Extreme Flow In-Line Variable Speed Brushless Fuel Pump 5 GPM Fitment | 5.0 GPM at 45 PSI | High-Flow Fuel Pump

Overview

The Fuelab PRO Series Extreme Flow In-Line Variable Speed Brushless Fuel Pump is engineered to deliver exceptional fuel flow and efficiency for high-performance Subaru builds and other demanding applications. Rated for up to 3400+ horsepower, this pump provides a reliable 5.0 gallons per minute (GPM) flow at 45 PSI, making it ideal for turbocharged and high-output naturally aspirated engines that require consistent fuel delivery under extreme conditions. Its universal fitment ensures compatibility across a wide range of platforms, including Subaru WRX, STI, BRZ, and more.

Designed with precision and durability in mind, the pump features a high-precision spur gear pumping mechanism combined with a lightweight, super-efficient brushless DC motor. This motor reduces current draw and eliminates wear-prone brushes, ensuring long-lasting performance even with fuels like low-sulfur diesel, ethanol, and methanol. The billet aluminum construction with MIL-A-8625 Type II anodizing adds corrosion resistance and strength, while the compact size and included T-style mounting brackets simplify installation.

For Subaru enthusiasts pushing the limits of power, this pump’s variable speed operation controlled via PWM input allows precise fuel delivery tailored to engine demands without the need for additional voltage regulators or controllers. This results in improved fuel efficiency, reduced heat generation, and reliable operation during spirited driving or track use. The Fuelab PRO Series pump is a robust solution that supports high horsepower builds and advanced tuning strategies.
