The AEM LPH High Flow In-Tank Fuel Pump is engineered for high-performance naturally aspirated and forced induction EFI vehicles. This pump delivers an impressive 400+ liters per hour (106+ GPH) at 40 PSI while drawing only 12 amps, making it one of the highest-flowing 39mm body pumps available.
It maintains excellent flow under boosted conditions, pushing 330+ LPH at 70 PSI (13.5V) enough to support approximately 870+ horsepower on gasoline. Fully compatible with ethanol (up to E100) and methanol (up to M100), this pump is ideal for high-performance street, track, and race applications. The single barb outlet is designed for 5/16" ID hose, and the kit includes everything needed for a clean installation.
