Walbro F90000267 450 LPH E85 Fuel Pump
The Walbro F90000267 is a high-performance 450 LPH pump designed to support up to 750hp in FFV applications. It is an in-tank unit that is pump-only, suitable for ethanol blends and optimized for high-flow EFI applications. This model emphasizes reliability under E85 fueling conditions with dedicated compatibility for FFV configurations and robust fuel delivery, particularly in boosted or high-output builds.
AEM 50-1215 E85-Compatible High Flow In-Tank Pump (340 LPH)
The AEM 50-1215 is an in-tank, high-flow pump tested to 340 LPH at 40 PSI. It ships with a wiring harness, pre-filter, and O-rings and is tested for compatibility with ethanol fuels up to E100 and methanol fuels up to M100. It is designed for naturally aspirated and forced induction engines, offering reliable performance for high-performance street and track applications while maintaining ethanol compatibility and ease of installation.
Walbro Hellcat 525LPH F90000285 Fuel Pump
The Walbro Hellcat series provides a 525 LPH capacity in a universal, in-tank design. Sold as a pump-only unit, the Hellcat pumps are widely used for high-horsepower applications requiring robust fuel delivery in E85-compatible builds. Note the labeling reflects TI Automotive rebranding, indicating continued use of Walbro’s proven high-performance components with ethanol compatibility.
Aeromotive 11540 340 Series Stealth In-Tank Pump
The Aeromotive 11540 340 Series is an in-tank, high-output pump designed to exceed standard flow rates by over 30%. It delivers more than 340 LPH at 40 PSI, supports EFI and carbureted setups, and fits into many hanger assemblies. It’s well-suited for engines using power adders and EFI systems seeking reliable high-flow operation with compatibility for E85 and other ethanol blends.
TERA PUMP E85 Barrel Transfer Pump
The TERA PUMP E85 Barrel Transfer Pump is a rechargeable, portable transfer pump designed for ease of use with fuel barrels. It features a 5-foot discharge hose, a lever-action nozzle, and compatibility with E85 for fast transfer from barrels to cans or containers. It is suitable for emergency fueling, DIY fuel handling, and applications requiring a portable transfer solution rather than a vehicle-installed pump.
Buying Guide
- Fuel compatibility: Ensure the pump is rated for E85 and compatible with ethanol blends. Look for seals and materials rated for ethanol exposure to avoid swelling or degradation over time.
- Flow requirements: Match the pump’s flow rate to your engine’s needs. High-horsepower or boosted builds benefit from pumps closer to 340–450 LPH or higher, while lighter setups may operate effectively with lower-flow units.
- Installation type: In-tank pumps offer integrated fuel delivery with the vehicle’s fuel system, while transfer pumps are ideal for barrel-to-container fueling or auxiliary fueling tasks. Choose based on application and space constraints.
- Power and electrical considerations: In-tank units typically rely on vehicle wiring and may require a dedicated fuel pump controller. Transfer pumps are often portable but may require batteries or a powered source. Verify amperage and voltage requirements.
- Pressure and performance: Confirm the pump’s pressure output range aligns with your fuel rail pressure targets. Some high-flow units perform best in boosted or forced-induction setups where stable pressure is essential.
- Reliability and warranty: Opt for pumps with proven reliability in ethanol environments and a solid warranty. This is important for long-term performance in demanding conditions.
- Installation compatibility: Check vehicle compatibility, hanger or mount compatibility, and whether accessories (harnesses, pre-filters) are included or must be sourced separately.
- Maintenance considerations: In-tank pumps may require inspection of pre-filters and electrical connections. Portability and battery-powered pumps require battery management and charge considerations for repeated use.
When upgrading or replacing an E85-capable fuel pump, consider your target horsepower, planned fueling regimen, and whether you want an installation-friendly in-tank solution or a versatile transfer pump for fueling flexibility. The options above cover a range of use cases—from street and drag applications to portable fueling needs—while maintaining ethanol compatibility and solid flow performance.
