Safety First:
* Disconnect the negative battery cable before starting any work on the fuel system. This prevents sparks that could ignite fuel vapors.
* Work in a well-ventilated area to avoid inhaling fuel fumes.
* Wear safety glasses to protect your eyes.
* Use jack stands to safely support the vehicle. Never work under a vehicle supported only by a jack.
* Be aware of sharp edges and hot components under the car.
Tools You'll Likely Need:
* Jack and jack stands
* Socket wrench set (metric)
* Wrenches (metric)
* Fuel line disconnect tool (essential to avoid damaging the lines)
* Screwdrivers (Phillips and flathead)
* Pliers
* Drain pan
* Shop rags
* New fuel pump (ensure it's the correct one for your vehicle)
* Fuel filter (consider replacing this while you're at it)
* Safety glasses
* Gloves
General Steps (Consult your repair manual for precise details):
1. Preparation: Locate the fuel pump. On most 1985 Chrysler New Yorkers, it's located in the fuel tank, requiring tank removal. This is the most labor-intensive part of the job.
2. Fuel Tank Removal: This typically involves:
* Lowering the fuel tank (often requires disconnecting the fuel lines, vent line, electrical connectors, and tank straps).
* Consult your repair manual for the specific procedure; it often involves partially lowering the rear of the car to access the tank straps.
* Drain the fuel tank carefully into a suitable container.
3. Accessing the Fuel Pump: Once the tank is out (or sufficiently accessible depending on your car's design), you'll usually find the fuel pump assembly secured to the top or side of the tank. There might be retaining clips, bolts, or a combination of both.
4. Disconnecting the Fuel Pump: Carefully disconnect the fuel lines, electrical connector, and any other components attached to the pump. Use your fuel line disconnect tool to prevent damage.
5. Fuel Pump Removal & Installation: Remove the old fuel pump assembly. Carefully compare it to the new one to ensure proper installation. Install the new fuel pump assembly, paying attention to the orientation and securing it properly.
6. Reassembly: Reassemble everything in the reverse order of disassembly. Double-check all connections to ensure tightness and proper seating. Reconnect the fuel lines, electrical connector, and other components.
7. Fuel Tank Installation: Carefully lower the fuel tank back into place, securing it with the straps.
8. Refueling and Testing: Refill the fuel tank with gasoline. Reconnect the negative battery cable. Carefully check for leaks around the fuel lines and connections. Start the engine and check for proper fuel pressure and operation.
Important Considerations:
* Fuel Pressure: You might need a fuel pressure gauge to test the system after installation.
* Fuel Filter: Replacing the fuel filter is a good preventative measure at the same time.
* Repair Manual: A repair manual specific to your 1985 Chrysler New Yorker is invaluable. It will provide detailed diagrams, torque specifications, and troubleshooting guidance. Don't attempt this repair without one.
Disclaimer: This is a general guide and may not be completely accurate for your specific vehicle. Always consult your repair manual for precise instructions and safety precautions. If you are not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Improper fuel system repair can lead to serious injury or damage.
