SKU: 50-1235 Category:
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.

Features:

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