Here's a general overview. Specific steps and procedures might vary slightly depending on the engine and trim level. Always consult a repair manual specific to your 1995 Chrysler New Yorker for detailed instructions and diagrams. This is crucial for accurate and safe work.
Steps (General Outline):
1. Safety First: Disconnect the negative battery cable. This prevents accidental sparks. Allow the fuel system pressure to release. This often involves running the engine until it stalls after a few attempts at starting, though the process can vary based on your vehicle. Consider using a fuel pressure relief tool for quicker and safer pressure release. Once the pressure is relieved, wait 15-20 minutes to ensure any lingering fuel fumes disperse. Work in a well-ventilated area, away from open flames or sparks.
2. Access the Fuel Pump: This usually involves dropping the fuel tank. The method for doing this varies: some models require removing the tank completely, while others allow for access through a trapdoor or access panel in the trunk (under the rear seat). Refer to your repair manual. You'll likely need to:
* Disconnect the fuel filler neck: This often involves unbolting clamps and disconnecting hoses.
* Disconnect the fuel lines: Use fuel line disconnect tools to avoid damaging the lines. Have a container ready to collect any remaining fuel in the lines. Do not use your mouth to siphon the fuel lines.
* Disconnect electrical connectors: Disconnect the fuel pump wiring harness.
* Remove tank straps: Carefully loosen and remove the straps or bolts securing the fuel tank. The tank may be heavy, so have a helper if possible. Support the tank carefully as you lower it.
3. Remove the Fuel Pump: The fuel pump is typically accessed from the top of the fuel tank. It's usually held in place by a retaining ring or a clamp. You might need special tools to remove the ring or clamp. Once removed, the fuel pump assembly should come out.
4. Replace the Fuel Pump: Carefully remove the old fuel pump from the assembly. Install the new fuel pump, ensuring it's correctly seated. Be mindful of any o-rings or seals that need to be replaced to prevent leaks.
5. Reassembly: Carefully reverse the steps to reinstall the fuel pump assembly, fuel tank, and all connections. Double-check all connections to ensure they are secure and properly seated. Make sure to tighten all bolts and clamps appropriately.
6. Reconnect the Battery: Reconnect the negative battery cable.
7. Prime the System (Important): After reassembly, you may need to prime the fuel system. This often involves turning the ignition key to the "ON" position several times (without starting the engine) to allow the pump to fill the lines. Check for leaks.
8. Test: Start the engine and check for proper operation. Listen for the fuel pump to run when the ignition is turned on. Look for any leaks around the fuel lines and tank.
Tools You'll Likely Need:
* Socket set
* Wrenches
* Fuel line disconnect tools
* Fuel pump removal tool (if necessary)
* Jack stands (for safety)
* Safety glasses
* Gloves
* Drain pan
* Repair manual specific to your 1995 Chrysler New Yorker
