The AEM 50-1215 is a 340LPH in-tank fuel pump in a 65mm diameter body with a short offset inlet design and mounting hooks for universal in-tank basket installation. At 340 liters per hour at 43 psi, the AEM 50-1215 supports high-horsepower gasoline and ethanol builds without requiring a larger fuel pump basket or custom fuel system fabrication. The 50-1215 is fully compatible with E85 and other ethanol-blend fuels, making it a preferred direct upgrade for naturally aspirated, turbocharged, and supercharged applications replacing failed or undersized factory fuel pumps. Note: The AEM 50-1215 is not CARB compliant and is intended for off-road or competition use only where applicable.

AEM Performance Electronics has developed aftermarket performance electronics and fuel system components for over 30 years from Hawthorne, California. The AEM fuel pump line is engineered for high-demand applications where factory fuel pumps cannot sustain adequate fuel pressure under boost or at elevated horsepower levels. AEM fuel pumps are used by professional race teams and performance builders worldwide in turbocharged, supercharged, and naturally aspirated builds running gasoline and E85.
The AEM 50-1215 is rated at 340 liters per hour (LPH) at 43 psi. This flow rate is sufficient to support approximately 500-600 horsepower on gasoline, or somewhat less on E85, depending on the specific fuel system configuration and injector sizing.
Is the AEM 50-1215 compatible with E85?Yes. The AEM 50-1215 is fully compatible with E85 and ethanol-blend fuels. The internal pump components are designed to withstand the corrosive properties of high-ethanol fuels that damage non-compatible pumps over time.
What is the body diameter of the AEM 50-1215?The AEM 50-1215 uses a 65mm body diameter. This is a common standard size used in many OEM and aftermarket fuel pump baskets, allowing drop-in installation without requiring a new basket assembly in most applications.
Does the AEM 50-1215 come with a pre-filter?Yes. The AEM 50-1215 kit includes an inlet pre-filter strainer that attaches to the pump inlet to protect the pump from large debris particles that may be present in the fuel tank.
Is the AEM 50-1215 a direct drop-in replacement for my stock fuel pump?The AEM 50-1215 is a universal 65mm in-tank pump with a short offset inlet and mounting hooks. Whether it is a direct drop-in depends on the specific vehicle's basket design and dimensional clearances. Most performance builds use the 50-1215 as an upgrade in an aftermarket or compatible OEM basket rather than a simple one-for-one swap.
Does the 50-1215 work on a daily driver street car?The AEM 50-1215 can be used in street vehicles as an upgraded fuel pump, but note it is not CARB compliant and may not be legal for street use on emissions-tested vehicles in California and some other states. Confirm legality for your application before installation.
What horsepower level does the AEM 50-1215 support on gasoline?At 340 LPH the AEM 50-1215 generally supports up to approximately 500-600 horsepower on gasoline, depending on fuel pressure, injector duty cycle, and system efficiency. Actual supported power will vary by build and fuel system configuration.
Does the AEM 50-1215 include a wiring harness?Yes. The AEM 50-1215 kit includes a pre-wired wiring harness for connection to the vehicle's fuel pump circuit. Review the included wiring diagram to match the harness connectors to your vehicle's fuel pump connector type.
