2000 Ford Explorer Fuel Pump Removal: A Complete Step-by-Step Guide

The bottom line: Removing the fuel pump on a 2000 Ford Explorer requires dropping the fuel tank or cutting an access hole in the cargo floor. The fuel pump is located inside the fuel tank, and there is no external access panel from the factory. This guide will walk you through the entire process, from preparation to installation, so you can get the job done safely and correctly.

Before You Start: Safety and Preparation

Removing a fuel pump involves working with gasoline, which is highly flammable. Safety should be your number one priority. Always work in a well-ventilated area, and keep a fire extinguisher nearby. Disconnect the negative battery terminal before starting any work on the fuel system. This prevents any accidental sparks or electrical shorts.

You will also need to relieve the fuel system pressure before disconnecting any fuel lines. The 2000 Ford Explorer uses a returnless fuel system, which means the fuel pressure can be high. Locate the fuel pump relay in the under-hood fuse box (Power Distribution Box) and remove it. Then, start the engine and let it run until it stalls. This depressurizes the system. After the engine stalls, try starting it one more time to confirm no fuel pressure remains.

Tools and Parts You Will Need

Before you start, gather the following tools and parts:

Tools:

  • Floor jack and jack stands
  • Socket set (metric and standard)
  • Screwdrivers (flathead and Phillips)
  • Fuel line disconnect tool (for quick-connect fittings)
  • Ratchet straps or a transmission jack (for lowering the tank)
  • Safety glasses and gloves
  • Drain pan for fuel
  • Shop towels or rags

Parts:

  • New fuel pump assembly (recommended to buy a complete unit, not just the pump)
  • New fuel tank O-ring seal
  • Fuel filter (replace while you are at it)
  • Hose clamps (if needed for your specific model)

Step 1: Relieve Fuel System Pressure

As mentioned above, start by removing the fuel pump relay from the under-hood fuse box. The fuel pump relay is typically located in the Power Distribution Box, which is on the driver's side of the engine bay, near the battery. Start the engine and let it run until it dies. This relieves the pressure in the fuel lines. After the engine stalls, try starting it again to confirm there is no pressure left.

Step 2: Disconnect the Battery

With the fuel pressure relieved, disconnect the negative battery terminal. This is a critical safety step. It prevents any electrical short circuits while you are working near the fuel tank and fuel lines. Use a wrench to loosen the nut and remove the cable from the battery post.

Step 3: Access the Fuel Pump

The fuel pump on a 2000 Ford Explorer is located inside the fuel tank. There are two main ways to access it: dropping the fuel tank or cutting an access hole in the cargo floor. Most mechanics recommend dropping the tank because it is the safest and most reliable method. Cutting an access hole requires precision and is not recommended for most DIYers, as it can lead to structural issues and leaks.

Dropping the Fuel Tank:

  1. Drain the fuel tank – Use a siphon pump to remove as much fuel as possible. The less fuel in the tank, the lighter it will be and the easier it will be to handle.
  2. Raise the vehicle – Use a floor jack and jack stands to safely raise the rear of the vehicle. Make sure it is stable.
  3. Remove the exhaust system – The exhaust pipe and muffler are often in the way of the fuel tank. You may need to unbolt the exhaust hangers and lower the exhaust system to access the tank.
  4. Disconnect the fuel lines – The fuel lines are connected to the fuel pump module with quick-connect fittings. Use a fuel line disconnect tool to separate them. Be prepared for a small amount of fuel spillage.
  5. Disconnect the electrical connector – The fuel pump electrical connector is located on top of the fuel pump module. Unplug it carefully.
  6. Remove the fuel tank straps – There are two metal straps that hold the fuel tank in place. Use a socket and ratchet to remove the bolts or nuts holding the straps.
  7. Lower the fuel tank – Place a transmission jack or a floor jack with a piece of wood under the tank. Lower the tank slowly, supporting it with the jack. Once the tank is low enough, you can slide it out from under the vehicle.

Step 4: Remove the Fuel Pump Module

Once the fuel tank is on the ground, you will see the fuel pump module on top of the tank. It is held in place by a large locking ring or a series of bolts. Use a hammer and a flathead screwdriver (or a special tool) to turn the locking ring counterclockwise. If your model uses bolts, remove them with a socket.

Carefully lift the fuel pump module out of the tank. The module includes the fuel pump, the fuel level sending unit, and the fuel filter. Be careful not to damage the float arm or the fuel level sensor.

Step 5: Inspect and Replace

Once the fuel pump module is removed, inspect the inside of the fuel tank. Look for any debris, rust, or sediment. If you find debris, it is a good idea to clean the tank thoroughly. Use a clean shop towel to wipe out the inside.

Now, remove the old fuel pump from the module. The pump is usually held in place by a clip or a bracket. Transfer the new fuel pump to the module, making sure it is seated correctly. Replace the fuel tank O-ring seal with a new one. This is a critical step to prevent fuel leaks.

Step 6: Reinstall the Fuel Pump Module

Lower the new fuel pump module back into the fuel tank. Make sure the float arm is not bent and that the module is seated correctly. Install the locking ring or bolts and tighten them securely. If you are using a locking ring, tap it clockwise with a hammer and screwdriver to lock it in place.

Step 7: Reinstall the Fuel Tank

With the fuel pump module installed, lift the fuel tank back into position. Reconnect the fuel tank straps and tighten the bolts. Reconnect the fuel lines and the electrical connector. Make sure they click into place. Reinstall the exhaust system and any other components you removed.

Step 8: Test the System

Lower the vehicle from the jack stands. Reconnect the negative battery terminal. Reinstall the fuel pump relay into the under-hood fuse box. Turn the ignition key to the ON position (but do not start the engine). You should hear the fuel pump prime for about 2-3 seconds. If you hear it, the pump is working. If you do not hear it, check the fuel pump fuse and relay again.

Start the engine and let it idle. Check for any fuel leaks around the fuel pump module and the fuel lines. If everything is dry, take the vehicle for a short test drive to confirm the fuel pump is working correctly.

Frequently Asked Questions

Where is the fuel pump relay on a 2000 Ford Explorer?
The fuel pump relay is located in the under-hood fuse box (Power Distribution Box). It is a standard relay and is often labeled. If you are unsure, check the diagram on the underside of the fuse box cover.

Where is the fuel pump fuse on a 2000 Ford Explorer?
The fuel pump fuse is also in the under-hood fuse box. It is typically a 20-amp fuse. Refer to the fuse box diagram to confirm the exact location.

Do I need to drop the fuel tank to replace the fuel pump?
Yes, on a 2000 Ford Explorer, the fuel pump is only accessible by dropping the fuel tank. There is no factory access panel in the cargo area.

How long does it take to replace the fuel pump?
Expect the job to take 3-5 hours if you are doing it for the first time. Experienced mechanics can do it in 2-3 hours.

Can I replace just the fuel pump, or do I need the whole module?
You can replace just the pump, but it is highly recommended to replace the entire module. The module includes the fuel level sending unit and the fuel filter, which are common failure points. Replacing the whole module saves you from having to drop the tank again in the future.
