AEM 50-1215 E85-Compatible High-Flow In-Tank Fuel Pump — 340 LPH, Compact 39mm×65mm

This in-tank unit combines a small 39mm diameter footprint with a 65mm length to deliver sustained high flow for performance naturally aspirated and forced-induction vehicles. Internal components are selected to resist the reduced lubricity and corrosive tendencies of ethanol and methanol, and each pump is flow-tested at 340 lph at 40 psi before packaging. The assembly ships with a wiring harness, pre-filter, end cap, hose, clamps, O-rings and a rubber buffer sleeve for easier installation into vehicle-specific fuel modules.

How does this pump handle ethanol and methanol blends?

The AEM 50-1215 uses materials and internal design choices that tolerate lower-lubricity fuels and higher alcohol concentrations. AEM validates compatibility up to E100 and M100, so the pump resists premature wear and swelling that can occur with ethanol or methanol exposure.

• Tested for E100 and M100 compatibility
• Materials chosen to reduce alcohol-induced degradation
• Designed to maintain flow and pressure with high alcohol content fuels

Will it fit my vehicle and what comes in the box?

This model is designed for in-tank mounting and is vehicle-specific; check fitment for your car or fuel module. AEM includes the main pump plus installation components so you receive a near-complete assembly for retrofit or replacement tasks.

• Compact 39mm x 65mm body fits many factory fuel modules
• Includes wiring harness, pre-filter, hose, clamps and O-rings
• Supplied end cap and rubber buffer sleeve for secure installation

What performance can I expect and how is it tested?

This pump is flow-rated to 340 liters per hour at 40 psi, suitable for many high-demand fuel system upgrades. Each unit is bench tested to confirm the 340 lph flow at the stated pressure before it leaves the factory, giving you a verified baseline performance figure.

• Rated 340 lph at 40 psi for consistent fueling capacity
• Individual flow testing performed before packaging
• Intended for both naturally aspirated and forced-induction builds

How does the compact size benefit installation and fuel system design?

The small diameter and short length allow easier integration into confined factory fuel modules or custom in-tank setups. The compact form also helps maintain pump clearance and reduces the need for extensive fuel-shelf modifications.

• 39mm diameter fits many OEM baskets and modules
• 65mm length reduces intrusion into tank volume
• Pre-filter and buffer sleeve minimize installation adaptation

Who is this for: The AEM 50-1215 340lph E85-Compatible in-tank fuel pump is aimed at enthusiasts and professional tuners running high-flow fuel systems, vehicles converted to high-alcohol fuels, or anyone replacing a failing OEM in-tank pump where compact size and alcohol compatibility matter. Confirm vehicle-specific fitment and electrical requirements before ordering to ensure seamless installation and reliable operation.
