Replacing Fuel Pump In '99 Dodge Stratus: Step-By-Step Guide

If you're looking to replace the fuel pump on your 1999 Dodge Stratus, you'll first need to locate it inside the fuel tank. To access the fuel pump, you can either go through an access panel in the passenger compartment or remove the tank from the vehicle.

Before starting, be sure to disconnect the battery and drain the fuel tank. Once you've accessed the fuel pump, you'll need to disconnect the EVAP, return line, and electrical connector. Clean the area with compressed air to remove any debris, then release the retaining ring and lift out the pump and pump O-ring.

Install the new fuel pump, lubricate the O-ring, and secure the pump with the retaining ring. Reattach the EVAP, fuel return line, and electrical connector. Reconnect the battery and prime the fuel system by turning on the ignition several times. Finally, check for any fuel leaks and retighten any leaky fittings.

Disconnect the negative battery terminal and cable

Disconnecting the negative battery terminal and cable is one of the first steps to take when changing the fuel pump on a 1999 Dodge Stratus. Here is a detailed, step-by-step guide on how to do this:

• Locate the negative battery terminal: The negative battery terminal is usually marked with a "-" symbol and is typically black in colour. It is often located on the driver's side of the vehicle, near the wheel well.
• Gather the necessary tools: You will need a wrench or socket set to loosen and remove the nut that secures the negative battery cable.
• Disconnect the negative battery cable: Place the appropriate-sized wrench or socket over the nut and turn it counterclockwise to loosen and remove it. Once the nut is removed, carefully lift the cable away from the terminal. Be sure to avoid any contact between the positive and negative terminals, as this could result in a short circuit.
• Secure the cable: Place the disconnected cable in a safe location away from the battery, ensuring that it does not touch any metal surfaces. You may want to cover the terminal with a piece of electrical tape or a cable cover to prevent accidental contact.
• Verify disconnection: Before proceeding with the fuel pump replacement, ensure that the negative battery cable is securely disconnected. This step is crucial, as you do not want the battery to be active during the fuel pump replacement process.

By following these steps, you will have successfully disconnected the negative battery terminal and cable on your 1999 Dodge Stratus, allowing you to proceed with the fuel pump replacement safely.

Remove the fuel tank

To remove the fuel tank on a 1999 Dodge Stratus, you will need to drain as much fuel as possible. Then, disconnect the battery and remove the straps holding the tank in place. You will also need to disconnect the fuel lines, wiring harness, and the clamp that goes to the filler tube. Once the tank is loose, carefully lower it from the vehicle, using a jack to support and lower it to the ground.

• Drain the fuel tank as much as possible.
• Disconnect the negative battery terminal and remove the battery.
• Locate and remove the straps holding the fuel tank in place. There may be two straps with two bolts each.
• Disconnect the fuel lines, wiring harness, and the clamp that goes to the filler tube.
• Carefully lower the fuel tank from the vehicle. You may need to slide the tank forward during removal to allow the filler neck to clear the suspension cross-member. Use a jack to support and lower the tank to the ground.

Remember to perform this procedure in a well-ventilated area and avoid any sources of ignition. It is also important to release the fuel system pressure before beginning any work.

Disconnect the fuel filter lines from the pump

Disconnecting the fuel filter lines from the pump is a crucial step in changing the fuel pump on a 1999 Dodge Stratus. Here is a detailed, step-by-step guide on how to do this safely and effectively:

Before beginning any work on your Dodge Stratus, it is imperative to ensure your safety. Wear appropriate protective gear, including gloves and eye protection, and work in a well-ventilated area. Always release the fuel system pressure and refer to the service manual for specific instructions and safety precautions.

Step 1: Access the Fuel Pump

First, you need to access the fuel pump. This typically involves removing the fuel tank and locating the fuel pump module. Refer to your Dodge Stratus service manual for detailed instructions on how to safely remove the fuel tank and access the fuel pump.

Step 2: Locate the Fuel Filter Lines

Once you have accessed the fuel pump, you need to locate the fuel filter lines. These are the lines that connect the fuel pump to the fuel filter, which is responsible for removing impurities from the fuel before it enters the engine.

Step 3: Prepare for Disconnection

Before disconnecting the fuel filter lines, it is important to clean the surrounding area to remove any dirt or debris. This will help prevent any contaminants from entering the fuel system. Use a clean cloth or compressed air to ensure the area is free of debris.

Step 4: Disconnect the Fuel Filter Lines

Now, you can proceed to disconnect the fuel filter lines from the fuel pump. Gently pull or pry the lines away from the pump, being careful not to damage the connections. Some vehicles may have quick-connect fittings, while others may require tools to loosen or unscrew the connections. Refer to your service manual for specific instructions on disconnecting the fuel filter lines for your 1999 Dodge Stratus.

Step 5: Contain Spills

As you disconnect the lines, be prepared for any fuel spills. Have a suitable container or absorbent material ready to catch any fuel that may spill. Remember to dispose of any fuel-soaked materials properly and in accordance with local regulations.

Step 6: Clean the Connections

Once the fuel filter lines are disconnected, clean the connections on both the fuel pump and the lines. Use a clean cloth or cotton swab to remove any dirt, debris, or residue. This will help ensure that the connections are free of contaminants before installing the new fuel pump.

By following these steps, you can safely and effectively disconnect the fuel filter lines from the fuel pump on your 1999 Dodge Stratus. Remember to refer to your service manual for specific instructions and safety precautions throughout the process.

Remove the pump module and O-ring from the tank

To remove the pump module and O-ring from the tank of your 1999 Dodge Stratus, you will first need to release the fuel system pressure and disconnect the negative cable from the auxiliary jumper terminal. Next, remove the fuel tank and disconnect the fuel filter lines from the fuel pump module.

Now, you can remove the pump module and O-ring. Using a Special Tool #6856 Fuel Pump Module Ring Spanner, remove the locknut to release the pump module. Be careful, as the fuel in the reservoir may spill out when the module is removed.

Once the locknut is removed, simply lift out the fuel pump module and O-ring from the tank. Discard the old O-ring and replace it with a new one when installing the new fuel pump module.

Install a new O-ring and position the new pump module in the tank

To install a new O-ring and position the new pump module in the tank of a 1999 Dodge Stratus, follow these steps:

Firstly, ensure the seal area of the tank is clean. Place a new O-ring on the ledge between the tank threads and the pump module opening. It is important to make sure the alignment tab on the underside of the pump module flange sits in the corresponding notch in the fuel tank.

Next, while holding the pump module in position, install the locknut. Tighten the locknut to 40 ft-lb torque using a special tool, such as #6856 Fuel Pump Module Ring Spanner.

Now, install the fuel tank and fuel filter. Refer to your vehicle's Fuel Tank/Service and Repair manual for detailed instructions on this.

Finally, fill the fuel tank with clean fuel and check for leaks.

It is important to note that over-tightening the pump lock ring may result in a leak, so be careful not to over-tighten during installation.
