AEM 340LPH 65mm Fuel Pump Kit w/ Mounting Hooks – Ethanol Compatible

Part Details:

AEM’s 340LPH E85-Compatible High Flow In-Tank Fuel Pump is built with robust internal construction designed to withstand the low-lubricity characteristics of ethanol and methanol fuels. Each pump is tested prior to packaging and is intended for high-performance naturally aspirated and forced induction EFI applications.

Overview

Designed for in-tank mounting, this compact pump features a short body design (65mm length) with mounting hooks, making it a strong option for universal applications where fuel tank clearance is limited. A 39mm diameter and offset inlet design help fitment and simplify installation in many setups.

Key Features

• Fuel compatibility: Tested and compatible with ethanol fuels up to E100, methanol fuels up to M100, and all types of gasoline
• Flow rating: Each pump is tested to flow 340 LPH at 40 PSI before packaging
• Application: High output naturally aspirated and forced induction EFI vehicles
• Mounting style: In-tank design
• Compact size: 39mm diameter x 65mm length
• Installation-friendly: Offset inlet design to ease installation

Important Notes

• Pre filter fitment: AEM fuel pumps include a universal pre filter which may not fit certain vehicle applications.
  Refer to OEM recommendations for filter replacement for your vehicle.
• Electrical requirements: Factory fuel pump wiring may not be adequate to handle the current draw of AEM’s high flow pumps.
  Refer to the Electrical Requirements section in the instructions document.
  You can download a copy of the instructions from the BUY/INSTRUCTIONS tab on AEM’s product pages.
• Polarity check: Ensure the polarity of the electrical plug in your tank is correct if you choose to use it.
  If it is not correct, you can re-pin it or use the supplied plug.
• Application sizing: Although AEM’s high flow fuel pumps are the same physical size as many OEM fuel pumps,
  they may not be appropriate for a specific application. Verify fuel pump sizing for your vehicle before purchasing.
• No tank modifications: AEM does not condone or approve tank modification to accommodate a high flow fuel pump
  and cannot guarantee performance or operation if modifications are made.

Recommended Supporting Fuel Components

• Fuel Injectors – higher-flow fuel pumps are often paired with upgraded injectors to support increased fuel demand.
• Fuel Pressure Regulators – help maintain consistent fuel pressure when increasing fuel flow capacity.
• Fuel Rails – support balanced fuel distribution when upgrading injectors and overall fuel system capacity.
• Fuel Delivery Components – explore complete fuel system upgrades designed to work together.
