The Aeromotive 340 LPH In-Tank Fuel Pump (model 11540) is a 12V high-flow, turbine-style electric pump engineered to deliver reliable fuel volume for demanding EFI and carbureted applications.

Built to supply steady fuel pressure and generous flow for modified engines, this compact 39mm OEM-style in-tank pump supports naturally aspirated, turbocharged, and supercharged setups. It produces over 340 liters per hour at 40 PSI and is rated for gasoline and E85, making it a versatile upgrade for street and track vehicles. The pump ships as a complete installation kit to simplify swap-ins or custom fuel-hanger builds.

How much flow and pressure can this pump provide?

This Aeromotive unit delivers in excess of 340 LPH at 40 PSI, giving a substantial fuel supply for high-output engines. Performance remains consistent across a wide operating range so EFI systems get stable fuel delivery under varying load conditions.

• Flow: >340 LPH measured at 40 PSI
• Nominal operating voltage: 12V electrical system
• Reliable pressure performance across typical EFI demands

Will it fit my vehicle’s in-tank hanger or fuel assembly?

The pump uses a compact 39mm OEM-style body designed for select in-tank hanger assemblies. Fitment depends on your vehicle and hanger design, so check Aeromotive’s application catalog or consult a qualified installer before purchase.

• Compact 39mm form factor for common hanger compatibility
• Designed for replacement in compatible in-tank assemblies
• Reference Aeromotive application guide for exact vehicle fit

Is this pump compatible with modern fuels and control systems?

The turbine-style design handles gasoline and ethanol blends such as E85 and performs reliably whether used with pulse-width-modulated (PWM) or constant-voltage fuel control strategies. Its construction supports in-tank duty and minimizes pulsation for smoother delivery.

• Fuel compatibility: gasoline and E85
• Works with PWM (pulse-modulated) and constant-voltage systems
• Turbine design reduces noise and promotes steady flow

What comes in the box and how straightforward is the installation?

Aeromotive includes a ready-to-install kit to streamline the swap: universal filter sock, wiring pigtail, rubber hose, clamps, and a grommet. While the kit covers most basic needs, professional installation or an experienced DIYer familiar with in-tank work is recommended for safety and proper sealing.

• Included: universal filter sock, wiring pigtail, rubber hose, clamps, grommet
• Designed to plug into many existing hanger setups with minimal modification
• Professional installation advised for in-tank replacement tasks

Who is this for: The Aeromotive 11540 340 LPH in-tank pump is aimed at enthusiasts and professional builders upgrading fuel delivery for high-horsepower street cars, race vehicles, or heavily modified factory engines. It’s an excellent choice when higher flow, ethanol compatibility, and a compact OEM-style form factor are required. If you need precise vehicle fitment or are building a custom fuel system, validate compatibility via Aeromotive’s application catalog and consider installation by a qualified technician to ensure optimal performance and safety.
