Here's a general procedure, but always consult your owner's manual for specifics and safety precautions:
1. Safety First:
* Disconnect the negative battery cable. This is crucial to prevent sparks that could ignite fuel vapors.
* Work in a well-ventilated area. Fuel vapors are flammable and hazardous.
* Wear safety glasses. Fuel can spray unexpectedly.
* Have rags and appropriate containers ready. You will be dealing with fuel.
* Use jack stands. Never work under a vehicle supported only by a jack.
2. Locate the Fuel Filter:
* Crawl under the truck. The fuel filter is usually near the fuel tank, often on the driver's side frame rail. It's a cylindrical metal or plastic canister with fuel lines attached. Look for markings indicating "Fuel Filter."
3. Prepare for Replacement:
* Place a drain pan under the fuel filter. Some fuel will drain out.
* Loosen the fuel line connections. Use a wrench that fits the connector type. They might be clamps or quick-connect fittings. You may need a fuel line disconnect tool to avoid damaging the lines.
* Have some rags ready to soak up any spilled fuel.
4. Remove the Old Fuel Filter:
* Carefully loosen and remove the fuel filter. The filter may be held on by clamps or other fasteners.
5. Install the New Fuel Filter:
* Compare the new filter to the old one. Ensure they are identical.
* Install the new fuel filter. Make sure the arrow on the filter indicates the correct fuel flow direction.
* Tighten the fuel lines securely.
6. Reconnect and Check:
* Reconnect the fuel lines. Double-check that they are securely attached.
* Reconnect the negative battery cable.
* Start the engine. Listen for unusual noises and check for leaks around the fuel filter. Let the engine run for a few minutes. If there are leaks, turn off the engine immediately and re-check all connections.
Important Considerations:
* Fuel pressure: Some fuel systems have significant pressure. Releasing pressure may be necessary before disconnecting lines. Consult a repair manual for your specific engine. Failing to relieve pressure could result in fuel spraying unexpectedly.
* Repair Manual: A repair manual specific to your 2003 Ford Ranger XLT is highly recommended. It will provide detailed diagrams, torque specifications, and safety precautions. This response is a general guide and might not cover all variations.
If you are not comfortable performing this task yourself, take your vehicle to a qualified mechanic. Improperly handling fuel lines can be dangerous.
