We've run 2x of these pumps on a -8feed -8return fuel system. 55 base PSI on the FPR. 1650CC Fic injectors. Car started seeing 90%+ duty cycle after making 703WHP on a mustang dyno, 25PSI boost. Pump e85, likely 80%+ ethanol content. Diluting the E85 with pump gas would allow more WHP to be made.
 
The AEM 380lph High Flow, High Pressure Fuel Pump for high performance naturally aspirated and forced induction EFI vehicles.
 
The High Flow, High Pressure Fuel Pump can be installed externally or in-tank using optional hardware that is sold separately. 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 AEM 380lph fuel pump delivers incredible performance and value. AEM’s 380lph High Flow, High Pressure Fuel Pump is capable of supporting over 1,200 HP normally aspirated and a whopping 1,075 HP at 30 psi boost!* It flows 380 lph (100 gph) at 43 PSI, 340 lph (90 gph) at 73 PSI, and 270 lph (71 gph) at 120 PSI.
 
The AEM 380lph High Flow Fuel Pump is designed for use with gasoline or E85. Pure alcohol fuels can be used, but pump life may be diminished. 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.
 
Optional accessories that are sold separately include a -10 ORB fitting inlet pre-filter (for use with in-tank installations), and both -8 and -6 discharge adapters without integral check valves. Accessory fittings are hard anodized.
 
* Designed for high output naturally aspirated and forced induction EFI vehicles
* Popular “044 Style” physical configuration but with AN inlet & discharge port connections
* Maintains very high flow even at boosted fuel pressures; 340 lph @ 73 PSI (30 psi boost)
* Installs externally or in-tank
* Each pump individually tested to flow minimum of 380lph (100gph) @ 43 PSI
* For gasoline vehicles (pump life will be diminished when used with alcohol fuels)
* Kit includes fuel pump, -6 to -8 male AN discharge fitting with check valve, terminal nuts & boots, instructions
* Optional -10 ORB fitting pre-filter, -6 and -8 discharge adapters without the integral check valves
*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.
