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.

A properly designed fuel delivery system is the backbone of any high-performance engine build, ensuring the injectors or carburetor receive a consistent supply of fuel at the correct pressure regardless of engine load, RPM, or fuel demand. From factory replacement pumps keeping daily drivers on the road to high-flow in-tank modules supporting 1000-horsepower builds, the right fuel delivery components prevent lean conditions, injector damage, and fuel starvation at the worst possible moment. Modern EFI systems are particularly sensitive to fuel pressure variation, with even small drops causing misfires and power loss under hard acceleration. Whether you are restoring a factory system or engineering a purpose-built race setup, matching pump flow rate and fuel pressure regulation to your injector and engine requirements is essential. Popular Upgrades Top-selling fuel delivery components include Aeromotive Phantom in-tank fuel pump kits that retrofit into factory tanks without custom fa...

A fuel pump is the foundation of every fuel system, and matching pump flow capacity to your engine's actual demand is one of the most critical decisions in any EFI or performance build. Undersized pumps cause lean conditions under hard acceleration that damage pistons and injectors, while oversized pumps can pressurize the fuel system beyond regulator capacity and require additional return plumbing to handle excess flow. Modern in-tank brushless pump designs from Walbro, TI Automotive, and Aeromotive deliver high flow rates with lower current draw and longer service life compared to older brush-style commutator designs. Diesel lift pumps serve a different function, providing pressurized supply to the high-pressure injection pump while also filtering water and particulates, and selecting the right lift pump for your diesel platform directly affects injection system longevity. Popular Upgrades Top-selling fuel pumps include the Walbro 255 LPH and 450 LPH in-tank pumps for popular turb...
