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.

-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 @ 73 PSI (30 psi boost)
-Each pump individually tested to flow minimum of 400lph (105gph) @ 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.

Buen producto
Buen producto, limpia perfectamente el motor interno y se libera la suciedad en el cambio de aceite. no use todo el contenido, creo que es bueno usarlo en 2 cambios de aceite para una mayor eficiencia.

Great will use it over and over again
I will use this in every car I own from now. Cleaned it real well did exactly what it said so and my truck runs a lot better definitely can tell the difference.. it was work the extra oil and work. The bottle I bought came with instructions in English, which made it easy for me. The quality of it is light brake cleaner, but meant for engines and it ran great very easy to use this pour in.

Does its job.
Always a go to before oil changes. Helps remove some extra sludge/deposits. DO NOT DRIVE OR REV THE VEHICLE WHEN USNG THE PRODUCT, only idle for 10-15 min. Ive seen reviews where people drove with it potentially ruining the engine.

Calidad de limpieza al motor
Excelente producto, lo llevo usándolo un buen tiempo, en cada cambio de aceite, limpia bien por dentro del motor. Es fácil usarlo, hecharlo donde se llena el aceite del motor, y enciende el motor espere 10 minutos, y apague el motor, y vuelve a esperar 25 o 30 minutos para que se enfríe el motor, ya cumplido lo 25 o 30 minutos sacar el aceite viejo del motor. Listo, producto muy recomendable. Excelente funcionamiento, chevy silverado 2004
