AEM 50-1235 400 LPH E85-Compatible High-Flow EFI Fuel Pump Kit

AEM's 400LPH high flow fuel pumps were designed with high performance naturally aspirated and forced induction EFI vehicles in mind! They deliver the same high flow and reliable performance that AEM has become known for at very competitive price. Each pump is individually flow tested and guaranteed to flow 400+ LPH (106 GPH) at 40 PSI (13.5V), which on gasoline will support 1000+ horsepower!* The pumps also maintain their high flowrate even as system pressure increases flowing 330+ LPH at 70 PSI (13.5V) which will support approx. 870 HP* on gasoline! Please see the flow curves and current draw vs. fuel pressure graphs on the specs tab for more information. With their compact 39mm body (same size as Walbro 255), low amperage draw, 11mm inlets and 9mm barbed outlet's these fuel pumps were designed to replace the OEM fuel pump in many applications. The 50-1230 features a double barbed outlet that is ideal for 3/8-inch ID hose where the 50-1235 features a smooth barbed outlet that is compatible with 5/16-inch ID hose. Each pump includes a wiring harness, pre filter, end cap and rubber buffer sleeve.Note: Your vehicle's factory fuel pump wiring may not be adequate to handle the current draw of AEM's High Flow Fuel Pumps. Please refer to the Electrical Requirements section in the instructions document for proper wiring.Note: These pumps do not include integrated check valves. 400LPH @ 40 psi - Inline Inlet - E85 Compatible

• Highest flow 39mm body fuel pump on the market. Each pump individually flowed and guaranteed to deliver 400+ LPH (40 PSI, 13.5V)
• 100% Compatible with most fuels including: pump/race gasoline, ethanol (up to E100), methanol (up to M100)
• Maintains very high flow even at boosted fuel pressures; 330+ LPH (70 PSI, 13.5V) (30 psi boost)
• Both models feature a 9mm outlet barb with an 11mm inlet in-line with the outlet
• Highly efficient - pumps draw only 12A @ 40 PSI and 15A @ 70 PSI

The AEM 50-1235 400 LPH high-flow fuel pump is designed for high-performance naturally aspirated and forced-induction electronic fuel injection vehicles. Individually flow tested and guaranteed to deliver more than 400 LPH at 40 PSI and 13.5 volts, this compact 39 mm fuel pump can support more than 1,000 horsepower on gasoline, depending on the vehicle’s fuel system and engine calibration. It also maintains strong output at elevated fuel pressure, delivering more than 330 LPH at 70 PSI and 13.5 volts for applications producing up to approximately 870 horsepower on gasoline.

Designed as an OEM-style replacement for many applications, the AEM 50-1235 uses an 11 mm inline inlet and a smooth 9 mm barbed outlet compatible with 5/16-inch inside-diameter fuel hose. Its efficient design draws approximately 12 amps at 40 PSI and 15 amps at 70 PSI, helping provide reliable high-volume fuel delivery without excessive electrical demand. The pump is compatible with pump and race gasoline, ethanol blends up to E100, and methanol blends up to M100, making it suitable for a wide range of performance fuel systems.

The AEM 50-1235 fuel pump kit includes a wiring harness, pre-filter, end cap, and rubber buffer sleeve for installation flexibility. Verify that the vehicle’s factory fuel-pump wiring can support the pump’s current requirements; upgraded wiring may be necessary. This pump does not include an integrated check valve and is not approved for use on carbureted applications. Installation should follow the vehicle manufacturer’s procedures and AEM’s electrical requirements.

Features:

• High-Flow Performance: Delivers more than 400 LPH at 40 PSI and 13.5 volts for high-output EFI applications.
• Boost-Pressure Capability: Maintains more than 330 LPH at 70 PSI and 13.5 volts for forced-induction fuel systems.
• Broad Fuel Compatibility: Supports gasoline, ethanol blends up to E100, and methanol blends up to M100.
• Efficient Compact Design: Uses a 39 mm pump body, 11 mm inline inlet, 9 mm smooth barbed outlet, and low current draw for many OEM-style installations.
