This process is general and might vary slightly depending on the specific trim level and options on your truck. Always consult a repair manual specific to your 1987 Ford Ranger SuperCab for precise details and torque specifications. A Haynes or Chilton manual is a good investment.
Here's a general outline of the steps involved:
1. Safety First:
* Disconnect the negative battery terminal. This is crucial to prevent sparks that could ignite fuel vapors.
* Work in a well-ventilated area. Fuel vapors are highly flammable.
* Wear safety glasses and gloves.
* Have a fire extinguisher readily available.
2. Preparation:
* Gather your tools: This will include various wrenches (sockets and open-end), screwdrivers (Phillips and flathead), jack stands, jack, fuel line disconnect tools, safety glasses, gloves, rags, and possibly a fuel pump removal tool.
* Drain the fuel tank: This is essential to minimize spillage. Siphon the fuel into an approved container.
* Locate the fuel tank: It's typically under the bed of the truck.
3. Accessing the Fuel Tank:
* Raise and secure the truck: Use jack stands to safely lift and support the rear of the truck. Never work under a vehicle supported only by a jack.
* Remove the bed: This is often the most challenging part. You'll need to disconnect the taillights, possibly the tailgate, and likely numerous bolts securing the bed to the frame. Consult your repair manual for the exact location and type of fasteners. You may need help with this step due to the weight of the bed.
* Disconnect fuel lines: Use fuel line disconnect tools to safely separate the fuel lines from the tank. Be prepared for some fuel spillage; have rags ready. Mark the lines to ensure correct reinstallation.
* Disconnect the fuel tank vent line(s): These allow air to enter the tank as fuel is drawn out.
* Disconnect the fuel tank sending unit (fuel gauge): This usually involves electrical connectors and possibly a retaining clip.
* Disconnect the fuel tank straps: These secure the tank to the frame. They are typically bolts or straps that need to be loosened or removed.
4. Removing and Installing the New Tank:
* Carefully lower the fuel tank: Be mindful of the fuel lines and other components attached.
* Install the new fuel tank: Ensure the new tank is properly seated and the straps are securely fastened.
* Reconnect the fuel lines: Double-check that the lines are correctly attached and tightened.
* Reconnect the fuel tank vent line(s) and sending unit: Ensure all electrical connections are secure.
* Reinstall the bed: This will reverse the steps you took to remove it.
5. Final Steps:
* Lower the truck: Carefully lower the truck from the jack stands.
* Reconnect the negative battery terminal.
* Check for leaks: Carefully inspect all fuel connections for leaks.
* Refuel the tank: Fill the tank with fuel.
* Check the fuel gauge: Verify that the fuel gauge is working correctly.
Again, this is a generalized guide. A detailed repair manual specific to your 1987 Ford Ranger SuperCab is absolutely essential for safe and successful completion of this job. Incorrectly performing this repair could result in serious injury or damage to your vehicle. If you have any doubts, please seek professional assistance.
