Replacing Fuel Pump In 2003 Windstar: Step-By-Step Guide

The fuel pump in a 2003 Ford Windstar is located inside the fuel tank. To change it, you will need a hand-held vacuum pump, a fuel-approved container, a lock ring removal tool, and a standard screwdriver. First, disconnect the vacuum hose from the fuel pressure regulator. Then, remove the fuel from the tank using a hand siphon pump. Next, jack up the rear of the Windstar and support the fuel tank. Disconnect the tank straps, lower the tank, and disconnect the fuel lines. After that, detach the sending unit/pump assembly and remove the fuel pump from the assembly. Finally, mount the new pump, reassemble the fuel tank, and refill it with fuel.

Loosen the fuel filler cap

To loosen the fuel filler cap on your 03 Windstar, you will need a standard screwdriver. The fuel filler cap is located inside the engine compartment, on the fuel rail leading to the fuel injectors. Once you have located the cap, use the screwdriver to loosen it. This step is necessary to relieve the pressure in the fuel system before proceeding with the fuel pump replacement.

It is important to note that you should always take safety precautions when working on your vehicle, especially when dealing with the fuel system. Make sure to work in a well-ventilated area and avoid any open flames or sparks that could ignite the fuel. It is also recommended to wear safety goggles and gloves to protect your eyes and hands.

Before loosening the fuel filler cap, make sure the engine is turned off and allow it to cool down if it has been running recently. This will help prevent any accidental burns or injuries. Additionally, refer to your owner's manual or seek advice from a qualified mechanic if you are unsure about any part of the process.

Once you have successfully loosened the fuel filler cap, you can proceed to the next step of disconnecting the vacuum hose from the fuel pressure regulator, as outlined in the source instructions for changing the fuel pump in an 03 Windstar. Remember to work carefully and consult a professional if you have any doubts or concerns during the process.

Disconnect the vacuum hose

Disconnecting the vacuum hose is a crucial step in changing the fuel pump in a 2003 Ford Windstar. Here is a detailed, step-by-step guide to help you through the process:

Locate the vacuum hose

The vacuum hose is connected to the fuel pressure regulator, which can be found on the fuel rail leading to the fuel injectors inside the engine compartment. This is where you will need to focus your attention.

• Begin by carefully disconnecting the vacuum hose from the fuel pressure regulator. You can do this by hand.
• Once the vacuum hose is disconnected, take your hand vacuum pump and connect it to the fuel pressure regulator.
• Apply 25 inches of mercury (Hg) of vacuum to the regulator. This step is important to ensure the regulator is functioning correctly.
• After applying the vacuum, disconnect the hand vacuum pump from the regulator.
• Reconnect the vacuum hose to the fuel pressure regulator. Ensure that it is securely attached to avoid any leaks.

By following these steps, you will have successfully disconnected and reconnected the vacuum hose, allowing you to proceed with the next steps in changing the fuel pump in your 2003 Ford Windstar. Remember to work carefully and safely, especially when dealing with fuel system components.

Remove fuel from the tank

To remove fuel from the tank of your 03 Windstar, you will need a hand siphon pump and a fuel-approved container.

First, loosen the fuel filler cap. Then, remove as much fuel as possible from the fuel tank through the filler neck into the approved container using the hand siphon pump.

Jack up the rear of the Windstar

Jacking up the rear of the Windstar is a crucial step in changing the fuel pump. Here is a detailed, step-by-step guide on how to do it safely and effectively:

Firstly, you will need to get the necessary equipment ready. For this step, you will require a floor jack and two jack stands. Position the floor jack at the rear of the Windstar, and ensure it is on a level surface to provide a stable base for lifting.

Next, carefully jack up the rear of the Windstar using the floor jack. Take your time with this step, ensuring the vehicle is lifted slowly and evenly to maintain stability. Once the vehicle is lifted, securely place the two jack stands in the appropriate locations to support the vehicle.

Now that the Windstar is securely jacked up, you will need to support the fuel tank, which is located underneath the vehicle. Position the floor jack under the fuel tank and adjust it as needed to provide stable support.

At this point, you can proceed to the next steps of changing the fuel pump, which involve disconnecting the tank straps, lowering the fuel tank, and accessing the fuel pump for removal and replacement. Remember to exercise caution and refer to a qualified mechanic or a detailed guide if you are unsure about any steps in the process.

Lower the fuel tank and disconnect the tank straps

To lower the fuel tank and disconnect the tank straps, follow these steps:

First, jack up the rear of the Windstar using a floor jack and support it on two jack stands. Next, support the fuel tank with the floor jack and disconnect the tank straps using a ratchet, ratchet extension, and socket. Now, carefully lower the fuel tank just enough to disconnect the fuel lines, vapor line, and unplug the pump electrical connector from the fuel sending unit/pump assembly on top of the tank. Finally, lower the fuel tank completely and set it aside.

At this point, you can access the fuel pump for replacement. Be sure to work in a well-ventilated area and avoid any open flames or sparks, as the fuel system contains highly flammable vapours.
