Buyer’s Guide: What to Consider

Choosing the right E85 fuel pump depends on your power goals, mounting preference, and fuel system setup. Here are five key factors to consider.

• Flow Rate (LPH): Higher LPH supports more horsepower. For E85, aim for at least 340 LPH for moderate builds, and 450+ LPH for over 600 HP.
• In-Tank vs. External: In-tank pumps are quieter and easier to install in factory modules. External pumps offer easier access and higher flow but require mounting below the tank.
• Fuel Compatibility: Ensure the pump is rated for E85 or higher ethanol blends. Some pumps also work with methanol, race gas, and diesel for multi-fuel flexibility.
• Pressure Rating: Check the pump's flow at your system's operating pressure. Higher pressure reduces flow, so match the pump to your fuel pressure regulator settings.
• Installation Kit: Some pumps come with wiring, filters, and O-rings. Others are pump-only. A complete kit saves time and ensures proper fitment.

Conclusion

Selecting the best fuel pump for E85 comes down to your horsepower target and installation preference. For compact in-tank builds, the AEM 340lph is a reliable choice. If you need extreme flow for racing, the Walbro 485LPH handles over 900 HP.

For external setups, the OSIAS inline pump offers flexibility, while the OSIAS 525LPH kit is ideal for Hellcat upgrades. Match the pump to your system, and you’ll get consistent E85 performance.
