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. Features:
- Designed for high output naturally aspirated and forced induction EFI vehicles - 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 at 73 PSI (30 psi boost) - Each pump individually tested to flow minimum of 400lph (105gph) at 40 PSI - Compatible with Flex Fuel (E85/E90) and all types of gasoline (100% Alcohol fuels may diminish fuel pump life) - Kit includes fuel pump, check valve fitting, terminal nuts & boots, instructions*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.
