AEM 400 LPH High-Flow In-Tank EFI Fuel Pump Kit, Double Barb, Part Number 50-1230

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. Hi-Flow In Tank EFI Fuel Pump

• 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 50-1230 400 LPH High-Flow In-Tank EFI Fuel Pump is designed for high-performance naturally aspirated and forced-induction vehicles using electronic fuel injection. Each pump is individually flow tested and guaranteed to deliver more than 400 LPH at 40 PSI and 13.5 volts, supporting more than 1,000 horsepower on gasoline in properly configured fuel systems. At increased system pressure, it maintains more than 330 LPH at 70 PSI and 13.5 volts, supporting approximately 870 horsepower on gasoline.

With a compact 39mm body comparable to popular OEM-style high-flow pumps, the AEM 50-1230 is suitable for replacement applications where space is limited. Its efficient motor draws approximately 12 amps at 40 PSI and 15 amps at 70 PSI. The pump features an 11mm inlet and a double 9mm barbed outlet designed for use with 3/8-inch inside-diameter fuel hose. It is compatible with a wide range of fuels, including pump gasoline, race gasoline, ethanol blends through E100, and methanol blends through M100.
