AEM 400lph High Flow In-Line Fuel Pump (50-1005)
400LPH High Flow In-Line Fuel Pump by AEM
AEM's 400LPH AN Fittings High Flow, High Pressure Fuel Pump is designed for high performance naturally aspirated and forced induction EFI vehicles. It can be installed externally or in-tank using optional hardware that is sold separately (see Images tab and part numbers, below). It utilizes the industry standard “044 Style” envelope and -10 AN female inlet and -6 AN female outlet connections for easy installation on new applications and for quick replacement of existing competitor fuel pumps. The 50-1005 fuel pump delivers incredible performance and value.
AEM’s 400LPH High Flow, High Pressure Fuel Pump is capable of supporting over 1,200 HP normally aspirated and a whopping 860 HP at 30 psi boost!* It flows 400LPH (100 gph) at 40 PSI, 340LPH (90 gph) at 73 PSI, and 270LPH (71 gph) at 120 PSI. Complete flow curves from 35 to 120 PSI and current draw vs. fuel pressure charts are available in the Specs tab.
The AEM 400LPH AN Fittings High Flow Fuel Pump is rated for use with ethanol-blended fuels, (E85/E90) and all types of gasoline, but pump life will be diminished if used with 100% ethanol fuels. The inlet thread is a -10 AN female ORB (O-ring port fitting) and the discharge is a female -6 AN ORB (O-ring port fitting). A male -6 to -8 AN discharge fitting with integral high pressure check valve, terminal nuts, terminal boots and installation instructions are included.
*Power rating given using gasoline and assuming a base fuel pressure of 43 PSI, 13.5v at the pump with a BSFC of 0.5. Boost fuel pressure is assumed to be the base pressure of 43 PSI + boost pressure. Flow capability for horsepower support is ultimately dependent on fuel hose diameter, and system electrical voltage and amperage capabilities.

I made 525 WHp on a Honda K24 turbo motor, Above that I saw drop in fuel pressure.
but I'll give this pump a big thumbs up for supporting upto 500WHP,
it's not silent pump, you can hear it running within the cabin even its installed outside, gets even louder after a pull or 2.
for a 500whp setup, best inline pump one can buy.
cheapest 500whp pump ..
Amazing product Amazing customer service
Worked as described, also got some fittings and filters to go with it. Shipped quick and packaged is on point, expected from maperformance. Always my go to for big or small parts. Always satisfied with their work. Keep it up.
fast shipping!! The product works great!!
