Fuel Pump - 450lph - E85 In-Tank - Universal

The Fuel Pump – 450lph – E85 In-Tank – Universal is purpose-built for high-performance fuel system upgrades on vehicles running ethanol blends or demanding boost levels. Whether you're building a turbocharged daily driver, a track car, or a street-strip hybrid, this in-tank electric pump delivers the volume and pressure consistency needed to support aggressive tuning without fuel starvation. As a mechanic, you'll recognize that fuel delivery is the foundation of engine management—undersized pumps cause lean conditions, hesitation, and catastrophic engine damage. This 450-liter-per-hour unit addresses that vulnerability across universal mounting platforms.

This electric in-tank pump is explicitly rated for E85 ethanol fuel, a critical advantage for tuners running flex-fuel or full ethanol setups. E85 requires approximately 34% more fuel volume than gasoline to achieve stoichiometric ratios, making pump capacity non-negotiable in ethanol builds. The pump features a filter sock inlet that protects internal components from particulate contamination, extending service life in high-mileage or poorly maintained fuel tanks. At 450 lph (liters per hour), this pump provides ample margin on turbocharged four-cylinder and six-cylinder platforms, supporting fuel-injected engines up to roughly 550–600 naturally aspirated horsepower or 400+ boosted horsepower depending on fuel pressure regulation and injector sizing. The compact in-tank design (2.5 x 2.3 x 7.5 inches, 1.08 lbs) fits standard fuel tank sumps without extensive fabrication.

Installers benefit from the universal mounting configuration, which accommodates most OEM fuel tank baffles with minimal modification. This pump is ideal for owners upgrading carbureted or older fuel-injected vehicles to modern EFI, as well as enthusiasts converting to E85 on existing turbocharged platforms. Proper installation includes fuel line sizing (typically 5/16" or 3/8" diameter minimum to reduce pressure loss), inline fuel filtering, and a quality fuel pressure regulator set to the engine's specification. When paired with appropriately sized injectors and a tuned ECU map, the 450 lph capacity ensures consistent delivery across the RPM band and eliminates the fuel delivery limitations that often plague modified builds.
