Park your car in a well-ventilated area and turn off the engine.
Locate the fuel filter. In a 2002 Ford F-150, it is usually found under the truck, near the fuel tank.
Prepare your work area. Place a drip pan underneath the fuel filter to catch any spilled fuel. Wear gloves and eye protection to protect yourself.
Depressurize the fuel system. There might be residual pressure in the fuel line connecting to the fuel filter. To release this pressure, locate the Schrader valve on the fuel rail on the engine, and slightly press it downwards using a small flat-head screwdriver to release any leftover pressure.
Disconnect the fuel lines. There might be one or two fuel lines connected to the fuel filter, depending on your setup. Use fuel line wrenches to loosen and disconnect these lines. Be aware that some fuel may spill, so ensure the drip pan is positioned accordingly.
Remove the mounting bracket. The fuel filter might be secured with a mounting bracket or clamp. Remove the necessary bolts or screws using appropriate tools like a wrench or screwdriver.
Replace the fuel filter. Take out the old fuel filter and properly dispose of it. Install the new fuel filter in its place, ensuring the flow direction is the same as indicated on the filter housing. Do not over-tighten it to prevent issues such as a fuel leak.
Reconnect the fuel lines. Properly reconnect the fuel lines to the new fuel filter, ensuring an accurate and secure fit.
Start the engine and check for leaks. Turn on the ignition and let the engine run for a few seconds. Observe the fuel filter and connected lines for any fuel leaks. If you identify any, tighten the fittings and connections as necessary.
