AEM - High Flow In-Tank Fuel Pump

AEM - High Flow In-Tank Fuel Pump for EFI Vehicles 


AEM Performance Electronics has released its High Flow in-tank Fuel Pump for high performance naturally aspirated and forced induction EFI vehicles  (Part #50-1000). It delivers reliable performance and high volumes of fuel flow for roughly half the cost of comparable performance fuel pumps.

The AEM High Flow Fuel Pump flows 320 lph (84 gph) at 43 PSI and is capable of supporting over 1,000 HP at 43 PSI.* Flow curves from 35 to 90 PSI and current draw vs. fuel pressure charts are available at www.aemelectronics.com.



The AEM High Flow Fuel Pump is designed for in-tank mounting for use with gasoline and features a compact 39mm diameter that fits most applications. It has an offset inlet design that eases installations and includes a wiring harness, pre filter, internal fuel hose and clamps, end cap and rubber buffer sleeve. Every pump is tested to flow 320 lph at 43 PSI before it is packaged for sale.

AEM High Flow Fuel Pump Features:

  • Designed for high output naturally aspirated and forced induction EFI vehicles
  • In tank design
  • Tested to flow 320 lph @ 43 PSI
  • 39mm diameter fits most applications
  • Offset inlet design eases installation
  • Each pump individually tested
  • For gasoline vehicles (pump life may be diminished when used with E85 Fuel)
  • Kit includes fuel pump, rubber sleeve and end caps, pre filter, hose, clamps and flying lead



*Power rating given at 43 PSI, 13.5v at the pump with a BSFC of .5. Flow capability for horsepower support is ultimately dependent on fuel hose diameter, and system electrical voltage and amperage capabilities.

What is the MSRP on one of these?

@ Garret: Price on their website currently shows TBA. A call or email should tell you for sure on the price. I'm sure it won't be too long before there's an official MSRP.

The Aeromotive stealth pump seems to flow just a little more and can sustain more at higher psi. The AEM does draw less amps.

The price is the major factor.

Listed at $100 on Jegs.

that is a really good price. Just about the same as a Walbro but much better performance, and its still an in-tank. Thats pretty good.

Should be quieter, too, since it's a turbine pump instead of a gear pump.

These pumps like the Walbro? Run low on gas and it will burn up the pump?

So... any idea how much power this pump would support on E85? On a turbo G35...
