M18x1.5 Inlet - M12x1.5 Outlet

Part Number: 50-1009

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. AEM's 400LPH High Flow, High-Pressure Fuel Pump (AEM 50-1005) is capable of supporting over 1,200 HP normally aspirated and a whopping 860 HP at 30 psi boost!* It flows 400LPH (100 gph) at 40 PSI, 340LPH (90 gph) at 73 PSI, and 270LPH (71 gph) at 120 PSI. Complete flow curves from 35 to 120 PSI and current draw vs. fuel pressure charts are available in the Specs tab. The AEM 400LPH AN Fittings 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.

Features and Benefits

• Designed for high output naturally aspirated and forced induction EFI vehicles
• Popular "044 Style" physical configuration but with AN inlet & discharge port connections
• Maintains very high flow even at boosted fuel pressures; 340LPH @ 73 PSI (30 psi boost)
• Installs externally or in-tank
• Each pump individually tested to flow minimum of 400LPH (100gph) @ 40 PSI
• Compatible with Flex Fuel (E85/E90) and all types of gasoline (100% Alcohol fuels may diminish fuel pump life)

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. You can download a copy of the instructions below. 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. The Vehicle Search function should be used as a reference only. It is imperative that you check the fuel pump sizing for your vehicle before purchasing an AEM High Flow Fuel Pump. AEM does not condone or approve of the modification of a tank to accommodate a High Flow Fuel Pump and cannot guarantee the pump's performance or operation if any modifications are made.
