Can I use any fuel pump?

As long as a fuel pump provides the Flow Rate your engine needs at the pressure your Fuel Injected or Carbureted system requires, it will work just fine. It is just a matter of deciding which one works best for your installation.

How do I know which fuel pump I need?

Are all fuel pumps the same?

Fuel pumps have different flow rates at different voltages. As voltage increases so does the speed of the fuel pump which will increase the flow of a pump at any given pressure. Because of this it is good practice to see how a pump is rated at a given voltage. Most cars will produce about 13.5 volts when running.

What happens if you put to big a fuel pump?

It is not possible for the factory regulator to bleed off the pressure fast enough when an upgraded fuel pump moves so much fuel. As a result, the injectors spray more fuel than they should, which results in higher fuel pressures. As a result, the engine runs poorly and the air to fuel ratio is too high.

What is the difference between fuel pumps?

The biggest difference between electrical and mechanical fuel pumps is that mechanical pumps rely on moving parts to pull fuel out of the tank and into the engine, whilst electrical pumps use electricity and computer power to push fuel to the engine.

Don't Ruin Your Car or Truck With This Fuel Pump Hack!

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.

What is a good aftermarket fuel pump?

For the best fuel pump, we recommend the TopScope Fuel Pump. This fuel pump is durable, reliable, and includes a fuel pressure regulator. For a budget-friendly fuel pump, the Yoneda Electric Fuel Pump 12V is an ideal substitute. The fuel pump is easy to use and works with a variety of vehicles.

Do you need a tune after upgrading fuel pump?

no tune needed. make sure you do a fuel filter as well when you do the pump. the FPR will regulate the pressure, injectors regulate the ammount of fuel used and the excess will return to the tank.

Does fuel pump affect acceleration?

Irregular resistance within the fuel pump motor can lead to your car slowing down and being unable to accelerate. Failing to accelerate is a good sign that your vehicle's fuel pump needs inspection.

Can a fuel pump be adjusted?

Should the fuel pump timing be required to be changed, then the shims fitted underneath the fuel pump would be changed. If shims are added the fuel pump will inject later, and visa versa for removing the shims.

How do you fix a fuel pump without replacing it?

How do I choose a mechanical fuel pump?

When selecting a mechanical pump we need to consider the RPM at which the pump will operate and the specific target RPM for Peak Torque and Peak HP for the engine. Typically the mechanical pumps are operated at ½ crankshaft speed.

Are Walbro fuel pumps universal?

One of the most famous and widely of Walbro's universal external pumps is the GSL392 255LPH High Pressure fuel pump. The GSL392 has been extensively used for High performance and Racing applications, and is the most popular universal external pump.

How long do a fuel pump last?

It takes gas from the gas tank and sends it to the engine so your car, truck, or SUV can start and run. Your vehicle's fuel pump should last at least 100,000 miles or more.

How much does it cost to fix a fuel pump?

The average cost for a fuel pump replacement is between $220 and $1,062, depending on vehicle and age. Labor costs are estimated between $124 and $260, while parts are priced between $95 and $854. Estimates do not include taxes and fees.

Can a car run without a fuel pump?

Without a fuel pump, the engine wouldn't get a fuel delivery, which is proven when a fuel pump isn't working. This will either cause your car to stall where it sits or you'll have poor fuel mileage, an indication that possible fuel pump repair or replacement is necessary.

Will a bigger fuel pump increase fuel pressure?

An upgraded fuel pump may move so much fuel, the factory regulator cannot bleed off the pressure fast enough. This leads to higher than desired fuel pressures which means the injectors are spraying more fuel than intended. The consequence is an overly rich air to fuel ratio and a poorly running engine.

Can a bad fuel pump damage engine?

You notice lower gas mileage.

Another symptom of a bad fuel pump is poor fuel efficiency. Damaged or worn components in the fuel pump can let excess fuel into the engine that goes to waste.

Do I need a tune for a fuel pressure regulator?

A: Yes, you will need a retune after installing the kit.

How important is it to use a fuel pump in a certain vehicle?

An in-tank fuel pump greatly reduces the risk of fire. Electrical components, such as the fuel pump, can spark and ignite fuel vapors, but liquid fuel will not explode. For this reason, positioning the fuel pump inside the tank, submerged in fuel, is the best placement for the fuel pump.

What does Lph mean on a fuel pump?

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.

Is a electric fuel pump better than mechanical?

-When do you need an electric fuel pump? Usually, a mechanical pump is preferred over an “aftermarket” electric fuel pump. They tend to be more reliable. However, sometimes that won't work.

What psi should my fuel pressure be?

Fuel pressure for most vehicles should stay in a 5- to 10-psi range.

What psi should a high pressure fuel pump be?

Typically, a high-pressure GDI pump creates about 2,000 psi. The sensor and the PCM help regulate the pressure to keep the fuel pressure at an ideal level for the engine in real time.
