Fuelab 93903 H/E Series SAE Flange Mount DC Brushless In-Tank Fuel Pump 550 LPH 1250 HP

The Fuelab 93903 is a high-efficiency SAE flange mount in-tank DC brushless fuel pump designed for high-performance applications up to 1250+ horsepower. This speed-controllable twin screw pump delivers 550 liters per hour (500 LPH at 45 PSI, 13.5V) while consuming less than 10 amps of current, making it one of the most efficient single-pump offerings available.

Key Features:

• Twin screw rotor pumping mechanism with DC brushless motor technology
• Speed controllable for variable flow requirements
• Maximum operating pressure of 125 PSI
• Compatible with gasoline, diesel, methanol, and ethanol fuels
• High flux density Neodymium rare earth magnets
• No brushes to wear out or corrode - ideal for low-sulfur diesel
• Wet motor design with no dynamic shaft seals
• Superior priming capabilities and greater resistance to cavitation (vapor lock)
• Higher efficiency means less current draw and reduced noise
• Lightweight design at only 2.4 lbs

This pump features a 4-inch diameter 10-bolt SAE flange mounting pattern and requires an acceptable tank depth range between 7.75 and 16 inches. Intended for OEM fuel tank or reservoir applications, this system requires an inlet straining filter, mating surface, mounting hardware, and seals (typically sourced by tank manufacturer). Backed by Fuelab's limited lifetime warranty.
