Product Details

Part Number: 50-1009
Brand: AEM
Color: Black

The AEM 50-1009 is a high-capacity inline fuel pump designed to support demanding fuel delivery needs for high-performance naturally aspirated and forced induction EFI vehicles. With a flow rate of 400 liters per hour (approximately 105 gallons per hour) at 40 PSI, this pump ensures a consistent fuel supply even under elevated pressures and boost conditions. It is capable of supporting over 1,200 horsepower naturally aspirated and up to 860 horsepower at 30 PSI boost, making it ideal for performance applications requiring reliable high-volume fuel flow. The pump features an M18x1.5 female inlet and M12x1.5 male outlet thread configuration, with a physical size similar to OEM pumps, allowing for straightforward installation in many vehicles. It includes essential components such as the pump itself, wiring terminals, check valve fittings, and installation instructions for a complete setup. The pump can be mounted externally or in-tank, offering flexibility for custom or OEM-style installations.

Designed for versatility, this pump supports all types of gasoline and E85/E90 flex fuels, though using 100% alcohol-based fuels may reduce its lifespan. Its high flow capabilities remain consistent at increased boost pressures, with flow rates of 340LPH at 73 PSI (30 psi boost) and 270LPH at 120 PSI, supported by detailed flow curves and current draw charts available in the specifications. While similar in size to many OEM fuel pumps, it is recommended to verify compatibility with your vehicle before installation using the vehicle search feature on the AEM website. The pump is individually tested to ensure a minimum flow of 400LPH at 40 PSI, guaranteeing performance and reliability for high-output applications. This product is not CARB-approved and must be acknowledged accordingly during installation, suitable for aftermarket use where local regulations permit. It is a premium choice for enthusiasts seeking a durable, high-flow fuel pump capable of supporting substantial horsepower gains and sustained operation under boost.

  • Flow Rate: 400 liters per hour (105 GPH) at 40 PSI for high-volume fuel delivery
