AEM 50-1009 high flow fuel pump 400 lph at 3 bar, E85 compatible

The AEM 50-1009 is a very high output performance fuel pump designed for gasoline and ethanol fuels such as E85. It is one of our most popular tuning fuel pumps for a reason: it supports extremely high power levels even on ethanol and performs reliably in demanding setups.

• High flow fuel pump for gasoline and E85 ethanol setups
• Flow rate 400 lph at 3 bar
• Strong flow at higher pressure, 340 lph at 5 bar
• Can be installed inline or as an in-tank pump
• Built-in check valve on the outlet
• 60 mm body diameter with Bosch 044 style dimensions

What does it do

When building a high power engine, fueling capacity quickly becomes a limiting factor. The AEM 50-1009 delivers strong and consistent fuel flow while maintaining output at higher pressure levels, making it an excellent choice for E85 conversions and large turbo setups where you want maximum fueling headroom and reliability.

This pump can be installed either inline or inside the fuel tank. The pump is supplied with an outlet check valve which helps maintain pressure in the system and improves overall performance in demanding use.

Dimensionally compatible with the Bosch 044 fuel pump, making it suitable for many Bosch 044 style brackets and surge tank setups.
