Aeromotive Brushless Spur Gear 3.5 In-Tank Fuel Pump Universal - 18394

The Aeromotive Brushless Spur Gear 3.5 In-Tank Fuel Pump (18394) is a high-performance universal fuel pump designed for demanding EFI and carbureted applications. Featuring true variable speed operation and a new integral spur-gear pumping mechanism, this brushless pump delivers exceptional fuel flow with reduced current draw at higher pressures. The adjustable in-tank design fits fuel tank depths from 9.4 to 17.4 inches and includes an external brushless controller for clean installation, improved reliability, and cooler fuel operation. Capable of supporting extreme fuel delivery demands, the system provides up to 90 PSI continuous operating pressure and 150 PSI peak pressure for boosted applications while offering extended service life when running methanol or ethanol fuels.
