400 LPH Fuel Pump & Hanger Assembly

The 400 LPH Fuel Pump & Hanger Assembly from Holley is engineered for serious fuel system upgrades on high-performance and modified vehicles. This electric, in-tank pump delivers 400 liters per hour—a substantial flow rate designed for naturally aspirated engines, forced induction builds, and fuel-injected platforms requiring robust fuel delivery under sustained demand. Built as a complete hanger assembly, it integrates directly into Sniper EFI fuel tanks, eliminating the hassle of sourcing separate components and ensuring OEM-quality fitment and sealing from the factory.

This pump features 1/4 inch NPT inlets and outlets, industry-standard ports that allow seamless integration into aftermarket fuel systems and custom plumbing configurations. The cadmium-plated construction resists corrosion in fuel tanks, ensuring longevity in both gasoline applications and ethanol-blended fuels. Electric operation means no belt drive or mechanical complexity—just clean 12-volt power delivery that responds instantly to ECU demand. The hanger assembly securely suspends the pump inside the tank, isolating it from fuel sloshing while maintaining consistent suction and pressure delivery throughout acceleration, braking, and cornering events.

Builders and tuners running Sniper EFI fuel systems will find this 400 LPH assembly an ideal foundation for engine builds in the 400–600 hp range, especially those incorporating turbochargers or superchargers. The complete hanger eliminates fitment guesswork and provides reliable fuel supply for custom chassis, hot rods, and street performance vehicles. Installation is straightforward for anyone with basic fuel system experience—simply drop the assembly into a compatible Sniper EFI tank, connect the outlet to your fuel rail, and wire power through a quality fuel pump relay.
