1. Safety First:
* Disconnect the battery's negative terminal. This is crucial to prevent electrical shocks or accidental starting.
* Work in a well-ventilated area. Fuel vapors are flammable.
* Wear safety glasses.
2. Gather Tools and Supplies:
* New fuel pump: Ensure you get the correct one for your specific engine and year.
* Wrench set (metric or SAE, depending on your car): You'll need various sizes.
* Socket set: Useful for accessing bolts in tight spaces.
* Screwdrivers (Phillips and flathead):
* Fuel line disconnect tool: These help prevent damage to the fuel lines. If you don't have one, be very careful.
* Pliers: Channel-locks or slip-joint pliers can be helpful.
* Shop rags or absorbent towels: To clean up any spilled fuel.
* Jack and jack stands: To safely lift the vehicle.
* Drain pan: To catch any spilled fuel.
* New fuel filter (recommended): While you're at it, replace the filter.
* Repair manual (highly recommended): This will provide specific instructions and torque specifications for your vehicle.
3. Procedure (General Steps – Consult Your Manual for Specifics):
* Locate the fuel pump: On most slant sixes, the fuel pump is mounted on the engine block, typically near the distributor.
* Drain the fuel tank (partially): This will significantly reduce the amount of fuel you'll have to deal with. You can use a fuel pump to suck the gas out, or carefully siphon it.
* Disconnect the fuel lines: Carefully disconnect the fuel lines from the fuel pump. Use fuel line disconnect tools if possible to avoid damage. Have rags ready to soak up any spilled fuel. Mark the lines so you know which goes where when reassembling!
* Disconnect the electrical connection: Unplug the electrical connector from the fuel pump.
* Remove the fuel pump mounting bolts: These are usually accessed from the bottom or side of the engine. You may need to remove other components to access them.
* Remove the old fuel pump: Once the bolts are removed, the fuel pump should come loose.
* Install the new fuel pump: Carefully install the new fuel pump, ensuring it's properly seated.
* Reconnect the fuel lines: Attach the fuel lines, making sure you've connected them to the correct inlet and outlet ports. Tighten the connections securely.
* Reconnect the electrical connection: Plug the electrical connector back onto the new fuel pump.
* Reinstall any components you removed: Put back any parts you had to remove to access the fuel pump.
* Lower the vehicle: Carefully lower the vehicle from the jack stands.
* Check for leaks: Before starting the engine, carefully inspect all fuel line connections for leaks.
* Start the engine and check for leaks: After a few minutes of running, check again for leaks.
* Replace fuel filter (if doing so): Follow the instructions on your new fuel filter to install.
Important Considerations:
* Fuel pressure: Some fuel pumps require priming before the engine will start. Consult your repair manual for the correct procedure.
* Torque specifications: Use a torque wrench to tighten all bolts to the manufacturer's specifications to avoid damaging parts.
* Fuel system pressure: The fuel system may be under pressure. Take extra care when disconnecting the fuel lines.
This is a general overview. The specific procedure will vary significantly depending on the year and model of your Plymouth. Using a repair manual specific to your vehicle is absolutely essential for a safe and successful repair. If you're not comfortable working on your vehicle, it's always best to consult a qualified mechanic.
