What You'll Learn
Fuel pump connector removal
To remove the fuel pump connector on a 2007 Mustang, you will need to first locate the bleeder valve and attach a fuel pressure bleeder system into a bucket or gas tank to bleed off fuel pressure.
Next, use a flat screwdriver to unlock the fuel pump connector by pushing the red tab back and pulling the connector off. Be prepared to catch any fuel that is trapped in the line. Now, the locking ring must be spun counterclockwise to release the fuel pump from the gas tank. You can use a hammer and a brass punch or a wooden dowel to spin the locking ring. Try not to damage the locking ring so it can be reused.
Thoroughly clean the area around the fuel pump before removal to ensure no dirt gets in the fuel tank. Now, carefully pull up on the fuel pump but do not remove it completely, as the crossover fuel line tube is still connected. This is removed in the same way as the fuel line on top of the fuel pump.
After replacing the fuel pump, ensure all wires are secure and free of corrosion. You can use a multimeter to verify voltage readings at different points in the circuit. Check for signs of debris or blockages in the filter and inspect for any kinks or restrictions in the lines.

Fuel line removal
To remove the fuel line of a 2007 Mustang fuel pump, follow these steps:
Firstly, locate the bleeder valve and attach a fuel pressure bleeder system into a bucket or gas tank to bleed off fuel pressure. This is shown in Figure 1 of the Mustangforums guide.
Next, use a flat screwdriver to unlock the fuel pump connector. Do this by pushing the red tab back and pulling the connector off. Now, remove the fuel line connector by pushing in the green tab and pulling back. Be prepared to catch some fuel that is trapped in the line.
Then, spin the locking ring counterclockwise to release the fuel pump from the gas tank. You can use a hammer and a brass punch to help with this step, as shown in Figure 7 of the Mustangforums guide. Try not to damage the locking ring so that it can be reused.
Now, carefully pull up on the fuel pump, but do not remove it completely as the crossover fuel line tube is still connected. This is removed in the same way as the fuel line on top of the fuel pump.
Finally, thoroughly clean all surfaces and seals that are being reused to ensure that no leaks occur.

Fuel pump locking ring release
To release the locking ring of the fuel pump on a 2007 Mustang, you will need to spin the locking ring counterclockwise. This can be done using a hammer and a brass punch, as shown in Figure 7 of the Mustangforums guide. It is important to try not to damage the locking ring so that it can be reused.
Some users have reported difficulty in removing and replacing the locking ring. One user recommends using a friend to apply gentle downward pressure on one side and twisting the other side to achieve even pressure. Another user recommends using a fuel pump locking ring tool, which can be purchased or rented from AutoZone. A universal/straight-across 2-prong tool will not work for rings with 7 notches, so a 3-prong type is required.

- Reattach the fuel line by pushing the connector until you hear a "click" and see that everything is properly seated.
- Secure all wires connected to the fuel pump. Make sure they are free of corrosion and tightly connected.
- Verify voltage readings at different points in the circuit using a multimeter.
- Check for any signs of debris or blockage in the filter and inspect for any kinks or restrictions in the lines.
- Clean or replace any components as needed.
- Test the fuel pump to ensure it is functioning properly.
It is important to note that these steps are general guidelines, and it is always best to refer to the manufacturer's instructions or seek the assistance of a qualified mechanic for specific instructions and safety precautions.

Fuel pump replacement
Step 1: Safety First
As a safety precaution, always wear safety glasses and gloves. Work in a well-ventilated area away from any open flames or anything that could cause a spark, such as pilot lights and incandescent light bulbs. Keep a fire extinguisher nearby. Do not smoke.
Step 2: Locate the Fuel Pump
Park your vehicle on a firm, level surface and set the parking brake. The fuel pump is usually located inside the fuel tank, which can be accessed either under the carpet or beneath the back seat. In some cases, there may also be an access point inside the trunk.
Step 3: Relieve Fuel Pressure
Before removing the fuel pump, it is important to relieve the fuel pressure in the system. Turn off the engine and locate the fuel pump fuse, then remove the fuse and restart the engine to release the pressure.
Step 4: Disconnect the Battery
Disconnect the negative battery cable to avoid any sparks that could cause a fire.
Step 5: Drain the Fuel Tank
If there is fuel in the tank, drain it into an approved container.
Step 6: Remove the Fuel Lines
Disconnect the filler tube hose and the electrical connection to the pump. Be prepared to catch any fuel that is trapped in the line.
Step 7: Remove the Fuel Pump
Remove any retaining straps or bolts holding the tank in place and carefully lower it. Now, you can remove the fuel pump from the tank.
Step 8: Install the New Fuel Pump
Compare the new fuel pump with the old one to ensure you have the correct part. Clean all surfaces and seals that are being reused to prevent leaks. Install the new fuel pump and secure it with the pump retaining ring.
Step 9: Reassemble and Test
Raise the tank back into place and reconnect the wire connectors and fuel lines. Reinstall your dust cover, seat cushion, and connect your battery. Start the engine to test the new fuel pump and check for any leaks.
Troubleshooting:
If your new fuel pump is not working properly, there may be an issue with the wiring or fuel pump itself. Check for signs of debris or blockage in the filter and look for any kinks or restrictions in the lines. Verify voltage readings at different points in the circuit using a multimeter.
