How do you change a fuel pump on 1971 Plymouth Fury?

Replacing a fuel pump on a 1971 Plymouth Fury is a moderately challenging job requiring mechanical aptitude and some specialized tools. It's not a quick task and safety precautions are crucial due to working with fuel. Always disconnect the battery's negative terminal before starting any fuel system work.

Here's a general outline. This is not a comprehensive, step-by-step guide and should not be considered a substitute for a proper repair manual specific to your 1971 Plymouth Fury. Variations exist depending on engine type (e.g., 318, 383, 440). Consult a repair manual for your specific engine and model.

1. Preparation:

* Safety First: Work in a well-ventilated area. Have fire extinguisher readily available. Wear safety glasses and gloves.

* Gather Tools: You'll need socket wrenches (various sizes), adjustable wrench, pliers, screwdrivers (possibly), fuel line disconnect tools, new fuel pump, fuel line clamps, rags, and possibly a fuel pump installation tool (depending on the design).

* Locate the Fuel Pump: It's typically mounted on the engine block or frame near the fuel tank. Your repair manual will show its exact location.

* Drain the Fuel Tank (partially): This reduces the risk of spillage and makes the job easier. You can use a siphon pump to do this.

* Relieve Fuel Pressure: If your car has a fuel pressure regulator, release the pressure according to your vehicle's manual.

2. Access the Fuel Pump:

* Remove any components obstructing access: This might include parts of the exhaust system, heat shields, or other components depending on your specific engine and model. Your repair manual is crucial here.

* Disconnect Fuel Lines: Carefully disconnect the fuel lines from the old fuel pump. Use the proper disconnect tools to avoid damaging the lines or spilling fuel. Have rags ready to absorb any spilled fuel. Mark the lines to ensure correct reconnection.

3. Remove the Old Fuel Pump:

* Remove Mounting Bolts/Clamps: Unscrew the bolts or clamps holding the fuel pump in place. This can sometimes be tricky due to rust or corrosion. Penetrating oil may be helpful.

* Remove the Pump: Carefully remove the old fuel pump from its mounting location.

4. Install the New Fuel Pump:

* Install New Gaskets/Seals (if necessary): Your new fuel pump may include new gaskets or seals. Ensure they are properly installed.

* Mount the New Pump: Carefully mount the new fuel pump in its place, ensuring it's seated correctly.

* Secure the Pump: Tighten the mounting bolts or clamps to the specified torque (refer to your repair manual).

5. Reconnect Fuel Lines and Components:

* Reconnect Fuel Lines: Carefully reconnect the fuel lines to the new fuel pump, making sure they are properly seated and clamped. Double-check that you've connected them to the correct ports.

* Reconnect all other components: Reinstall any components removed in step 2.

6. Test and Verify:

* Reconnect the Battery: Reconnect the battery's negative terminal.

* Check for Leaks: Carefully inspect all connections for leaks.

* Start the Engine: Start the engine and check for leaks. Listen for any unusual noises from the fuel pump. Let it run for a while to verify that the fuel pump is working correctly.

Important Considerations:

* Repair Manual: A factory repair manual for your specific 1971 Plymouth Fury is invaluable. It will provide detailed diagrams, torque specifications, and step-by-step instructions tailored to your vehicle.

* Fuel Line Integrity: Inspect the fuel lines for cracks, damage, or deterioration while you have access to them. Replace any damaged lines.

* Fuel Filter: Consider replacing the fuel filter while you're working on the fuel system.

* Professional Help: If you are not comfortable performing this repair yourself, consider taking your car to a qualified mechanic. Working on fuel systems can be dangerous if not done properly.

This information is for guidance only. Always refer to a repair manual specific to your vehicle for detailed instructions and safety precautions. Incorrect installation can lead to serious issues, including fire. If you're unsure about any part of this process, seek professional help.
