The 400lph Metric High-Flow Inline Fuel Pump has an M18x1.5 female inlet and M12x1.5 male outlet. It utilizes the industry standard ?044 Style? envelope. It is capable of supporting over 1,200 HP normally aspirated and a whopping 860 HP at 30 psi boost!* It flows 400lph (105 gph) at 40 PSI, 340 lph (90 gph) at 73 PSI, and 270 lph (71 gph) at 120 PSI. Complete flow curves from 35 to 120 PSI and current draw vs. fuel pressure charts are available on the Specs tab.
The AEM 400lph Metric High Flow Fuel Pump is rated for use with ethanol-blended fuels, (E85/E90) and all types of gasoline, but pump life will be diminished if used with 100% ethanol fuels.

- Popular ?044 Style? physical configuration with metric fittings for direct replacement of 044 pumps!
- Maintains very high flow even at boosted fuel pressures; 340 lph @ 73 PSI (30 psi boost)
- Each pump individually tested to flow minimum of 400lph (105gph) @ 40 PSI
- For gasoline vehicles (pump life will be diminished when used with alcohol fuels)
- Kit includes fuel pump, check valve fitting, terminal nuts & boots, instructions
- Compatible with Flex Fuel (E85/E90) and all types of gasoline
- Weight: 35.8oz (1015 grams)
- Outside Diameter: 60mm OD
- External Materials: Black plated steel with laser etching
- Inlet Fitting: M18x1.5 female
- Outlet Fitting: M12x1.5 male
- PRV Activation: 150 PSI
- Impeller Design: Roller vane with ceramic end plate
- Connector Terminal: 6mm stud positive, 5mm stud negative
- Min Voltage Input: 10 volts
- Max Voltage Input: 18 volts
- Current Draw (40 psi): 9.73 amps no check valve, 10.68 amps with check valve (13.5v)
- Current Draw (120 psi): 16.07 amps no check valve, 17.13 amps with check valve (13.5v)
- Fuse: 25 amps (13.5v), 30 amps (13.5v) MAx
- Power rating given using gasoline and assuming a base fuel pressure of 43 PSI, 13.5v at the pump, 6.2 lbs/gal with a BSFC of 0.65. Boost fuel pressure is assumed to be the base pressure of 43 PSI + boost pressure. Flow capability for horsepower support is ultimately dependent on fuel hose diameter, and system electrical voltage and amperage capabilities.
- Your vehicle's factory fuel pump wiring may not be adequate enough to handle the current draw of AEM's High Flow Fuel Pump. Please refer to the Electrical Requirements section in the instructions document for proper wiring.
- Although AEM's High Flow Fuel Pumps are the same physical size as many OEM fuel pumps, they may not be appropriate for a specific application. You can consult the Vehicle Search function on our website to see whether a pump is recommended for your vehicle.
