Ford Mustang Fuel Pumps

The fuel injection system of your Ford Mustang supplies the exact amount of fuel by way of an electric fuel pump located in the fuel tank. The Ford Mustang fuel pumps are located in the fuel tank due to the fact that gasoline has a high boiling point under pressure. The stock Ford Mustang maintains a fuel pressure of around 39 PSI.

What are signs of a bad fuel pump?

If you are experiencing the following symptoms with your Ford Mustang, it may be time to replace your fuel pump:

  • Engine sputtering at high speeds: Since the fuel pump is responsible for supplying the motor with fuel at a consistent pressure when it starts to have problems, this can cause the vehicle to sputter, then return to normal after a few seconds.
  • Low pressure: An automobiles engine needs a specific amount of pressure to run smoothly. If the pressure is under the recommended level, the pump may be deteriorating.
  • Loss of power while going uphill: Sometimes, you may not notice problems at high speed, however, you may notice a loss of power while driving uphill.
  • The car surges forward without pressing the gas pedal further: Abnormal or irregular resistance within the electric motor of fuel pumps can cause the automobile to surge forward unexpectedly.
  • Decreased gas mileage: A change in fuel economy could be a sign that the release valve is failing to open. This builds up more fuel than is needed.
What kind of fuel pump is used for high performance?

If you are looking to get as much as you can out of your Ford Mustang fuel system, switching from the factory fuel pump to an in-line, high-performance fuel pump is necessary. These sort of aftermarket fuel pumps can raise the pressure from 39 PSI to 119 PSI. Although aftermarket parts are not Original Equipment Manufacturer or OEM parts, they are designed and produced by companies specializing in high-performance car parts.

What size of fuel pump do you need?

When you think of the size of fuel pumps, it isnt the physical size you need to figure out or necessarily the model and year of your Ford but how many gallons per hour of fuel it pumps. It can also be rated by liters per hour and pounds per hour, depending on the size of the vehicle. For a Mustang, youll be looking at the gallons or liters per hour.

When considering what kind of fuel pumps your Mustang needs, you first must contemplate what it is you want to achieve. Two factors come into play: horsepower or HP and brake specific fuel consumption or BSFC. Everyone understands the meaning of horsepower, but BSFC measures the amount of fuel used to produce each unit of HP. The average car will use one pound of fuel in producing one HP.

Furthermore, the average Ford production vehicle produces between six and eight PSI while ensuring reliable fuel supply. High-performance automobiles such as the Mustang require a more base fuel pressure. The reason being as your Mustang increases its power output, the amount of pressure needed to produce the required HP must increase equally. Additionally, the voltage supply must be compensated to make up for the extra power needed to operate larger fuel pumps than those offered stock.
