Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery by removing the negative terminal to prevent electrical shock.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Remove Fuel Pump Assembly

Safely raise the vehicle and support it on jack stands.
Remove the fuel tank's protective shield if applicable.
Disconnect the fuel lines from the fuel pump assembly, using a line wrench to avoid damage.
Unplug the electrical connector from the fuel pump.
Remove the retaining ring or bolts securing the fuel pump to the fuel tank.
Carefully pull the fuel pump assembly out of the tank.

3. Inspect and Replace

Inspect the fuel pump for signs of wear or damage; check the strainer and check valve.
If the pump is faulty, replace it with a new unit designed for the 2015-2020 Ford F-150.
Replace the fuel filter if it shows signs of clogging or heavy wear.
Reinstall the fuel pump assembly into the tank, ensuring the O-ring is in place to prevent leaks.
Secure the fuel pump with the retaining ring or bolts and reconnect the fuel lines and electrical connector.

4. Reassemble and Test

Reinstall the fuel tank shield if removed.
Reconnect the battery and install the fuel pump relay.
Turn the ignition key to the "On" position without starting the engine to prime the fuel system.
Check for leaks around the fuel pump and connections.
