Note: Some people have reported that it is possible to replace the fuel pump without dropping the tank, but this may depend on your body flexibility. It is recommended that you have a helper when reinstalling the tank.

Ensure the fuel tank is drained before removing the access panel

It is imperative to ensure that the fuel tank is drained before removing the access panel. This is a critical safety measure to prevent the risk of fire when working on the fuel pump. Here are some detailed steps to ensure the fuel tank is drained:

First, park the car on a level surface and engage the parking brake. This will ensure the car remains stationary during the draining process. Next, locate the fuel tank drain plug. This is usually found at the bottom of the fuel tank. Place a suitable container under the drain plug to collect the fuel. Make sure you use a container that is specifically designed for storing fuel and can handle the volume of fuel in the tank.

Once you have the container in place, carefully remove the drain plug using the appropriate tools. Fuel will begin to drain from the tank, so be cautious and have rags or absorbent materials ready in case of any spills or leaks. Allow the fuel to completely drain from the tank. Depending on the amount of fuel in the tank, this may take some time. Do not rush this step as you want to ensure that the tank is as empty as possible.

After the tank is drained, securely replace the drain plug. Properly dispose of the drained fuel according to local regulations and guidelines. Never pour fuel down the drain or into the environment as it can cause serious harm. Now that the tank is drained, you can proceed to remove the access panel to reach the fuel pump. Remember to take all necessary safety precautions when working on the fuel system, including wearing appropriate protective gear and ensuring adequate ventilation.

By following these steps, you can ensure that the fuel tank is drained before removing the access panel, making it safer to work on the fuel pump. Always exercise extreme caution when handling fuel and refer to a professional mechanic if you have any doubts or concerns.

Check for fuel leaks and that the problem is solved

Once you've replaced the fuel pump on your 1990 Chrysler LeBaron, you'll need to check for fuel leaks and confirm that the problem is solved. Here's a detailed guide to help you through the process:

Check for Fuel Leaks:

• Start by locating the fuel tank and pump. The fuel pump on a 1990 Chrysler LeBaron is located inside the fuel tank.
• With the car turned off and the engine cool, inspect the area around the fuel tank and pump for any signs of moisture or fuel accumulation. Look for darkened spots on concrete or blacktop surfaces, or discoloured and dying foliage if the car was parked on grass.
• Pay close attention to the smell of gasoline. A distinct sweet or aromatic odour may indicate a fuel leak.
• Check the fuel gauge. If the fuel level drops significantly while the car is turned off and parked, it could be a sign of a fuel leak.
• Examine the fuel lines for any damage, rust, or improper installation that could lead to a fuel leak.
• Inspect the gas cap to ensure it is properly sealed. A loose or malfunctioning gas cap can trigger the Check Engine Light and cause fuel vapours to escape.
• If you notice any signs of a fuel leak, do not attempt to drive the car. Fuel leaks can be dangerous and may lead to fire or explosion hazards. Contact a professional mechanic or roadside assistance for support.

Confirm the Problem is Solved:

• After replacing the fuel pump, start the engine and listen for any unusual noises. A properly functioning fuel pump should operate quietly.
• Check the fuel pressure at the fuel injectors. Adequate fuel pressure is necessary to keep the engine running smoothly.
• Ensure that the pump is delivering enough fuel. Low pressure or insufficient fuel delivery may indicate a problem with the pump or a clogged fuel filter.
• Verify the electrical circuit of the pump. Insufficient voltage or a bad connection may require replacing the circuit.
• If the fuel pump and related components appear to be functioning correctly, take the car for a test drive. Pay attention to the engine's performance and whether it stalls or loses power.
• If the car runs smoothly without any issues, your problem is likely solved. However, continue to monitor the vehicle's performance and fuel efficiency over the next few days to ensure that the issue doesn't persist.

Remember, working with the fuel system can be dangerous due to the risk of fire. Always take the necessary precautions and prioritize your safety. If you're unsure or uncomfortable at any point, it's best to consult a professional mechanic.
