What is a high flow fuel pump?

AEM’s High Flow In-Tank Fuel Pump is designed for high performance naturally aspirated and forced induction EFI vehicles. It delivers reliable performance and high volumes of fuel flow for roughly half the cost of comparable performance fuel pumps.

Does a high flow fuel pump require a tune?

No. A tune is not required and you will not run rich.

Can I put a larger fuel pump in my car?

By adding a BAP and setting it at max, you are able to get more fuel flow (due to higher voltage and more current driving the pump) and hence pressure when needed out of your stock fuel pump. You can also get more fuel flow and hence more pressure when needed by putting in larger flow fuel pumps.

Can a fuel pump increase horsepower?

Horsepower As horsepower increases so does the volume of fuel required to support that power. A good estimator of volume to power is approximately 10 hp per gallon or 2.64 hp per liter. For example if your pump flows at 50 gph it should be able to support a 500 hp engine (50 x 10 = 500).

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.

What does a high flow fuel pump do?

A high pressure fuel pump is much safer for your car as well as cheaper in the long run. Fuel pumps that have a higher pressure have it because more often than not, they are placed in the actual fuel tank. This will help to prevent any fires starting.

Can I upgrade my fuel pump without a tune?

Yes, just install it, no tune needed, nothing will change. The fuel pressure regulator controls the pressure. Fuel pressure should not change assuming the pump is not out flowing the regulators ability to bleed off pressure.

Do you need a tune for an aftermarket fuel pump?

Do you NEED to tune the car, no not at all. Keep in mind here guys that you still have certain mechanical constraints on the system. The lines are the same, the FPR is the same, and the rail are the same so the volume and pressure are still basically the same.

Can a fuel pump be too powerful?

Using the wrong fuel pump that delivers excess pressure can cause problems ranging from poor performance and lower gas mileage to flooding and carburetor damage. When the pressure is only a little over the required amount, your vehicle may sputter when you first accelerate from a stopped position.

How much horsepower will a 340LPH fuel pump support?

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.

How much horsepower will a 255lph fuel pump support?

A 255lph pump delivers about 410lb of fuel per hour so that’s enough to feed about 750 crank hp with forced induction (assuming 0.55 BSFC) and 900 crank hp NA (assuming 0.45 BSFC).

How many GPH is a 700 hp?

Theoretically, the mechanical pump could provide the (approx) 60 gallons per hour that the engine would need, using the formula of 1/2 lb of fuel per horsepower per hour. That’s if you used a quality mechanical pump and not a stocker. So, 700 x . 5 = 350 gal.

What is inline high pressure fuel pump?

High pressure inline pumps feed a higher pressure continuously which is opposed by the fuel pressure regulator with no provisions for a return line. The system works well for performance purposes but falls short in terms of longevity. The in-tank electric fuel pumps use a regulator with a return line to the tank.

Is fuel pump in fuel tank?

The fuel pump is located in the fuel tank on modern cars, and problems can occur when the fuel pump either becomes clogged from sediment in the fuel tank or stops working due to wear, usually from working too hard or after long intervals of time. A fuel pump should last you at least 100,000 miles or longer.

What does fuel flow mean?

Fuel flow is the movement of oil or gas through delivery pipes. The valve controls fuel flow into the delivery pipe.

What is fuel pressure psi?

It’s to this Schrader valve that you’ll connect a fuel pressure test gauge to, to check the fuel pump’s pressure. With the key on, engine off (KOEO), the factory manual says fuel pump pressure should be between 30 to 45 PSI for the 5.0L and 5.8L V-8 engines. The KOEO fuel pressure for the 4.9L 6 cylinder is 45 to 60 PSI .
