3.5 Spur Gear Fuel Pump Brushless Design

The AEROMOTIVE 3.5 Spur Gear Fuel Pump with brushless design is a high-capacity in-line electric fuel pump engineered for high-performance fuel delivery systems. Rated at 1350 lb/hr at 9 psi, this pro-series pump delivers consistent, reliable fuel pressure to fuel-injected engines running on gasoline or E85 ethanol blend fuels. The brushless motor design eliminates contact wear common in traditional brushed pumps, extending operational lifespan and reducing maintenance requirements in demanding street and competition applications.

Built with 12 AN female O-ring inlet and 10 AN female O-ring outlet connections, this fuel pump integrates directly into professional fuel system plumbing without adapters. The high flow rate of 1350 lb/hr at 9 psi supports engines requiring robust fuel supply during acceleration, load changes, and sustained high-RPM operation. The brushless electric motor operates efficiently with minimal heat generation, critical for fuel system longevity. This pump is housed in a compact inline form factor measuring 5.35 x 4.4 x 10.05 inches and weighs 5.75 lbs, fitting standard fuel system layouts in street rods, race vehicles, and modern fuel-injected builds.

This pump is designed for builders and enthusiasts upgrading to high-flow fuel systems where OEM pumps cannot reliably maintain pressure under sustained boost, nitrous addition, or lean-burn tuning. The dual-fuel compatibility (gasoline and E85) makes it suitable for flex-fuel engine platforms. The AEROMOTIVE pro-series positioning targets serious performance applications where fuel delivery consistency directly impacts engine reliability and performance output. The brushless technology and sealed design provide durability in hot engine compartments and during extended track or autocross sessions.
