When you're pushing your engine to its limits, the last thing you want is to run out of fuel. That's why performance enthusiasts trust AEM's 400LPH High Flow Fuel Pump to deliver consistent, reliable fuel delivery under the most demanding conditions. This isn't just another upgrade—it's a critical component that can make the difference between a record-breaking pass and a frustrating engine cutout.
Whether you're running a naturally aspirated monster that's putting down serious horsepower or a turbocharged beast with massive boost pressure, the AEM 400LPH has you covered. With the ability to support over 1,200 HP in normally aspirated applications and a staggering 860 HP at 30 psi boost, this pump moves serious fuel when your engine needs it most. Its 60mm outside diameter ensures compatibility with most installations while maintaining the robust construction needed for high-pressure environments.
What really sets this pump apart is its consistent performance across varying pressure conditions. While lesser pumps might falter under pressure, the AEM 400LPH delivers 400 liters per hour at 40 PSI, maintains 340 lph (90 gph) at 73 PSI, and still provides 270 lph (71 gph) at 120 PSI. This means whether you're running low boost on the street or maxing out your turbo at the track, your engine gets the precise fuel delivery it needs for optimal performance.
This pump has earned its reputation in the performance community for good reason. It's equally at home under the hood of a daily-driven muscle car that sees occasional track days as it is in a purpose-built race car that lives at the drag strip. Enzymers appreciate the peace of mind knowing their fuel system won't be the weak link when they're pushing for that extra tenth of a second or that extra mile per hour.
Installation is straightforward, and with complete flow curves and current draw charts available in the specs tab, you can have confidence in your selection. When you choose the AEM 50-1005, you're not just buying a fuel pump—you're investing in reliability, performance, and the confidence that comes from knowing your engine will never run out of breath.
