liters per hour
Electric fuel pumps for EFI applications are rated in liters per hour, or lph. Factory electric fuel pumps can flow around 180-190 lph in early EFI cars, and high-performance, late-model Vette pumps can flow more than the popular “255-lph” aftermarket fuel pumps.

How much HP can a mechanical fuel pump support?

Although a good mechanical fuel pump can feed your engine for up to 400 horsepower, have an electric fuel pump can be added insurance. Most carbureted systems up to this horsepower range do not use a return line. Once you get above 450 horsepower, you might want to think about a return-style fuel system.

How much HP will a Walbro 450 support?

Walbro 450 High Pressure The 450 (F90000267) and 450 High Pressure (F90000274) will both Support 500+hp on E85 Fuel and 700+ on pump gas applications.

How much HP can a 340LPH pump handle?

The AEM 340LPH High Flow In-Tank Fuel Pump (PN 50-1000) flows 340 lph (84 gph) at 40 PSI and is capable of supporting over 1,000 HP at 43 PSI.

What Lph means?

Liters Per Hour. LPH. Amphibious Assault Ship (Helicopter) LPH.

How much HP will a Holley black pump support?

They are rotor/vane-style pumps designed to flow high volumes of fuel at low pressures, perfect for low- to high-horsepower carbureted applications. The Holley Red pump flows 97 gph and supports 425 hp, while the Blue pump flows 110 gph and supports 550 hp. Stepping up to the Black pump yields 140 gph and 750 hp.

Do all 340 stealth pumps flow 340 LPH?

All 340 Stealth Pumps are tested multiple times in production to ensure each individual pump does flow 340 lph and meets all quality and performance specs, 100%. So, putting aside all the variables]

What is the fuel pressure of the AEM 340lph high flow fuel pump?

The AEM 340LPH High Flow In-Tank Fuel Pump (PN 50-1000) flows 340 lph (84 gph) at 40 PSI and is capable of supporting over 1,000 HP at 43 PSI.* Please see the flow curves and current draw vs. fuel pressure graphs on the specs tab for more information.

Can a 340 EFI pump be made to work in any vehicle?

A: Again, nothing is impossible, any EFI pump may possibly be made to work in any vehicle application if sufficient and correct modifications are made to fit and support it. However, Aeromotive cannot recommend what specific modifications must be made for vehicles that are not listed in the 340 Stealth Pump application guide.
