AEM 400LPH High Pressure Fuel Pump -6AN Female Out, -10AN Female In

AEM 400LPH High Pressure Inline Fuel Pump (-10AN In / -6AN Out)

Boost fuel delivery with the AEM 400LPH High Pressure Fuel Pump (-10AN In, -6AN Out). Supports up to 1,200 HP NA / 860 HP boosted. E85 and Flex Fuel compatible.

The AEM 400LPH High Flow, High Pressure Fuel Pump (Part # 50-1005) is engineered for high-output naturally aspirated and forced-induction Electronic Fuel Injection (EFI) applications. Designed using the iconic "044 style" 60mm outer diameter footprint, this pump upgrades conventional barbed connections to leak-free, heavy-duty AN fittings—featuring a female -10AN ORB inlet and a female -6AN ORB outlet.

Capable of supporting over 1,200 HP on naturally aspirated builds and up to 860 HP at 30 PSI of boost, this pump maintains strong flow rates even under high system pressures (delivering 340 LPH at 73 PSI base + boost pressure). Constructed with a durable black-plated steel body, a roller vane impeller design, and a ceramic endplate, it supports gasoline, race fuels, and ethanol blends (E85/E90) for street, drag, or track environments.

Best Uses

1. High-Horsepower Forced Induction: Turbocharged and supercharged street/strip builds requiring reliable fuel flow at elevated manifold boost pressures.
2. Flex Fuel & E85 Applications: Performance engines running high-octane ethanol blends that demand higher volume fuel delivery.
3. Surge Tank & External Fuel Systems: Dual-pump or single external inline surge tank configurations where standard Bosch 044 pumps are replaced or upgraded.
4. Custom Race Fuel Cell Setups: Motorsports applications using -10AN supply and -6AN pressure lines with dedicated plumbing.

Features

1. High Flow Output: Individually bench-tested to flow a minimum of 400 LPH (100 GPH) at 40 PSI.
2. Integrated AN Threaded Ports: Built with a female -10AN ORB inlet and female -6AN ORB outlet to eliminate hose barb failures under high pressure.
3. "044 Style" 60mm Outer Diameter: Features standard 60mm physical dimensions, fitting existing 044-style mounting brackets and fuel cradles.
4. Roller Vane & Ceramic Endplate Design: Built for mechanical longevity and heat tolerance across varying fuel temperatures.
5. Universal Mount Versatility: Configured for external inline mounting or in-tank drop-in setups using optional pre-filter accessories.

Benefits

1. High-Pressure Performance: Delivers superior flow retention under load, maintaining 340 LPH even at 73 PSI (43 PSI base + 30 PSI boost) to prevent lean conditions.
2. Massive Power Support: Provides sufficient fuel volume to feed up to 1,200 HP NA and 860 HP under forced induction on a single pump setup.
3. Fuel Compatibility: Safe for standard pump gas, race gas, and E85/E90 flex fuel setups without rapid seal degradation.
4. Secure Connection Points: Threaded AN fittings prevent blow-offs, dynamic leaks, and pressure drops common with clamped rubber lines.
5. Complete Install Hardware: Includes the male discharge fitting with an integral check valve, protective terminal boots, and electrical mounting hardware for a straightforward installation.
