Universal 400LPH High-Flow Inline Fuel Pump by AEM

AEM’s 400lph Metric High Flow, high-pressure Inline Fuel Pump (PN 50-1009) is the perfect direct replacement upgrade for 044 pump users who want more fuel flow for their high-performance vehicle!

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.
