The AEM 400lph Metric High-Flow Inline Fuel Pump (PN 50-1009) is a direct replacement for 044 pumps and offers an impressive increase in fuel flow for high performance vehicles. It features an M18X1.5 female inlet and M12x1.5 male outlet, with the popular “044 Style” physical configuration. Capable of supporting over 1,200 HP for normally aspirated engines and 860 HP at 30 psi boost, this pump provides 400lph at 40 PSI, 340 lph at 73 PSI, and 270 lph at 120 PSI. It is also compatible with Flex Fuel (E85/E90) and all types of gasoline, but using 100% ethanol fuels will decrease pump life. Each pump is individually tested and is designed for high output applications. The AEM 400lph Metric High Flow Fuel Pump meets the demands of ethanol-blended fuels and comes with a check valve
