AEM 340LPH In Tank Fuel Pump Kit - Ethanol Compatible

AEM 340LPH High Flow In-Tank Fuel Pump Kit - E85 Ethanol Compatible

Upgrade your high-output engine with the AEM 340LPH Ethanol-Compatible In-Tank Fuel Pump Kit. Designed to support up to 1,000 HP with E85, methanol, or gasoline.

The AEM 340LPH In Tank Fuel Pump Kit - Ethanol Compatible is engineered for high-performance naturally aspirated and forced induction Electronic Fuel Injection (EFI) vehicles. It delivers a reliable flow rate of 340 liters per hour (84 GPH) at 40 PSI, making it strong enough to support engines generating over 1,000 HP.

Designed specifically to combat the low lubricity of alternative fuels, this pump is fully tested and compatible with E100 ethanol, M100 methanol, and standard pump gasoline. Its compact 39mm diameter body fits directly into most factory fuel tank assemblies without major modifications. Every kit includes a wiring harness, pre-filter sock, internal fuel hose, clamps, and rubber sleeve to ensure a complete, seamless installation.

Best Uses

1. Flex-Fuel & E85 Conversions: Ideal for vehicles transitioning to high-ethanol fuel blends (E85/E100) requiring extra fuel volume.
2. High-Horsepower EFI Builds: Perfect for high-output naturally aspirated or forced-induction (turbocharged/supercharged) engines producing up to 1,000 HP.
3. Track & Motorsport Applications: Supports aggressive fuel demands and high system pressures under sustained high-RPM driving.

Features

1. 340 LPH High Flow Rate: Delivers a continuous 340 liters per hour at 40 PSI to keep high-output engines supplied with fuel.
2. Ethanol & Methanol Compatibility: Purpose-built internal construction tested for E100, M100, and gasoline.
3. Compact 39mm Body: Features a standard 39mm diameter and offset inlet design for simple drop-in fitment.
4. 1,000+ HP Capability: Flow dynamics capable of supporting extreme power output under elevated system pressures.
5. Complete Install Kit: Package includes pre-filter fuel sock, wiring plug, submersion-rated hose, hose clamps, and rubber buffer sleeve.

Benefits

1. Prevents Lean Fuel Conditions: Maintains consistent fuel delivery under high boost or high demand to protect against engine damage.
2. Versatile Fuel Support: Enables seamless switching between pump gas, race gas, and flex-fuel/E85 without degrading internal pump components.
3. Drop-In OEM-Style Fitment: Fits inside the stock fuel tank module of most popular vehicle platforms with minimal fitting hassle.
4. Proven Unit Reliability: Every single unit is individually flow-tested to 340 LPH at 40 PSI before leaving the factory.
5. Cost-Effective Power Upgrade: Delivers big-pump volume and ethanol durability at a fraction of the cost of external surge tank systems.
