This fuel pump is intended for electronic fuel injection systems only. It is not suitable for
carbureted engines. The fuel pump is an in tank pump and not suitable for external use.
Pump flow and test information
Every AEM fuel pump is flow tested before it leaves the factory to ensure that it flows
nominal 320 LPH @ 43 PSI. The flow chart presented below is the result of flow testing
20 fuel pumps, eliminating the highest and lowest flowing samples and averaging the
balance of the flow data. The data presented is flow in pounds per hour (PPH), and
supported power at various fuel pressure levels. This test data is generated using the
AEM fuel pump, AEM Race Fuel Filter and an AEM universal fuel pressure regulator
with the optional .250” return orifice. The pump voltage is 13.5V and the current is 12
Amps for this test. The flow will be different at the engine because of losses through the
balance of the fuel delivery system. It is important to ensure that the hoses or lines for
the fuel delivery system are clean, not kinked, do not pass hot exhaust components and
are terminated correctly. We find inadequate fuel delivery often is the cause of
calibration errors that may be detrimental to engine life.
NEVER route fuel hoses through the interior of a car. Put bluntly, this is a dangerous
thing to do. Whenever possible, use a delivery tube to make the connection from the
pump discharge to the filter in the front of the car. The lines should be rated to withstand
at least twice the maximum pressure of the EFI system.
When routing fuel lines, it is imperative that they are protected from road hazards and
the exhaust system heat. The fuel line should NEVER be routed near battery cables.
Use clamps to secure AN hose every 15 inches, or 24 inches if a rigid tube is used.
The following table will help you determine which hose size is correct for your
application: These sizes are based on a nominal fuel pressure of 43 psi.
