2000 Mitsubishi Mirage Fuel Pump Location: A Complete Guide for DIY Owners

The fuel pump on a 2000 Mitsubishi Mirage is located inside the fuel tank. To access it, you need to remove the rear seat cushion and then the access panel on top of the tank, or alternatively, drop the entire fuel tank from underneath the vehicle. This in-tank design is standard for this model and helps keep the pump cool and protected from external damage. Knowing exactly where to find it and how to get to it can save you hours of frustration and expensive shop labor.

Why the Fuel Pump Is Inside the Tank

Modern vehicles like the 2000 Mitsubishi Mirage use an electric fuel pump mounted inside the fuel tank. This placement serves several important purposes. First, the fuel itself acts as a coolant, keeping the pump motor at a safe operating temperature. Second, submerging the pump reduces the risk of fire since the fuel vapors are contained within the closed system. Third, the pump is protected from road debris, salt, and physical impact that would quickly damage an externally mounted unit.

The 2000 Mirage uses a turbine-type electric pump that operates at 12 volts. It pushes fuel from the tank through the fuel lines and up to the engine's fuel rail. The pump delivers between 47 and 50 psi of pressure at idle, which is necessary for the fuel injection system to work correctly.

How to Access the Fuel Pump

There are two main ways to get to the fuel pump on a 2000 Mitsubishi Mirage. The method you choose depends on your tools and the layout of your specific vehicle.

Method 1: Through the Rear Seat Access Panel

This is the preferred method for most DIYers. It is faster and less messy.

  1. Park the vehicle on a level surface and turn off the engine. Let it cool down completely.
  2. Disconnect the negative battery terminal. This is a critical safety step that prevents accidental sparks while working near fuel.
  3. Relieve the fuel system pressure. Locate the fuel pump fuse in the fuse box and remove it. Then start the engine and let it run until it stalls. Turn the ignition off.
  4. Remove the rear seat cushion. The cushion typically lifts up and pulls forward. On some models, you may need to remove a few bolts.
  5. Locate the access door. Under the rear seat, you will find a metal or plastic cover plate. This is the access door to the fuel pump module.
  6. Remove the access door screws or bolts. Use a screwdriver or socket to remove the fasteners. Lift the cover off carefully.
  7. Identify the fuel pump. You will see a large cylindrical module with a black plastic cover and electrical connectors. This is the fuel pump assembly.
  8. Disconnect the fuel lines and electrical connectors. Be prepared for a small amount of fuel to spill. Have a rag handy.
  9. Remove the locking ring. Use a locking ring removal tool or a hammer and punch to turn the ring counterclockwise.
  10. Lift the pump module out. Gently raise the assembly out of the tank. Be careful not to bend the fuel level float arm.

Method 2: Dropping the Fuel Tank

If your vehicle does not have an access panel under the rear seat, or if you need to inspect the entire tank, you will need to drop the tank.

  1. Drain the fuel tank. Use a hand pump or siphon to remove as much fuel as possible. This makes the tank lighter and safer to handle.
  2. Raise the vehicle safely. Use a jack and jack stands. Never work under a vehicle supported only by a jack.
  3. Disconnect the filler neck hose. This is the large rubber hose that connects the gas cap to the tank.
  4. Disconnect the EVAP system hoses. There are small vapor lines that connect to the tank.
  5. Disconnect the electrical harness. The wiring for the fuel pump runs along the frame and connects to the top of the tank.
  6. Support the tank with a floor jack. Place a block of wood between the jack and the tank to distribute the weight.
  7. Remove the tank straps. There are usually two metal straps that hold the tank in place. Remove the bolts and lower the straps.
  8. Lower the tank slowly. Have a helper assist you. Watch for any hoses or wires that may still be connected.
  9. Remove the pump assembly. Once the tank is on the ground, you can access the pump from the top of the tank.

Tools You Will Need

Before you start the job, gather these tools:

  • Socket set with metric and standard sizes
  • Flathead and Phillips screwdrivers
  • Fuel line disconnect tools (plastic clip-style tools)
  • Locking ring removal tool (or a brass punch and hammer)
  • Floor jack and jack stands
  • Drain pan for fuel
  • Rags and shop towels
  • Safety glasses and gloves
  • Fire extinguisher

Safety Precautions for Fuel Pump Work

Working with gasoline is inherently dangerous. Follow these safety rules:

  • Work in a well-ventilated area. Gasoline vapors are heavier than air and can accumulate in low spots. Open the garage door or work outside.
  • Disconnect the battery. Remove the negative terminal before you start any work.
  • No open flames or sparks. Do not smoke, use a phone, or run any electrical tools near the fuel tank.
  • Keep a fire extinguisher nearby. Make sure it is rated for Class B (flammable liquids) fires.
  • Wear safety glasses. Fuel can splash into your eyes.
  • Relieve fuel pressure. Always release the pressure in the fuel system before disconnecting any lines.

Common Symptoms of a Failing Fuel Pump

If your 2000 Mitsubishi Mirage is experiencing any of these issues, the fuel pump may be going bad:

  • Engine cranks but will not start. This is the most common symptom. The pump is not delivering fuel to the engine.
  • Engine stalls unexpectedly. The pump may be failing intermittently, causing the engine to die while driving.
  • Loss of power under load. If the pump cannot maintain adequate pressure, the engine may feel sluggish, especially when accelerating uphill.
  • Whirring or humming noise from the fuel tank. A healthy fuel pump runs quietly. If you hear a loud whine or hum from the rear of the car, the pump bearings are likely failing.
  • Check engine light comes on. A low fuel pressure condition can trigger the check engine light. The code may indicate a lean fuel mixture.

Fuel Pump Relay Location

If you are troubleshooting a no-start condition, also check the fuel pump relay. On the 2000 Mitsubishi Mirage, the fuel pump relay is located inside the vehicle, under the dashboard, approximately centered in the vehicle. It is behind the dash panel, so you may need to remove the lower trim to access it. The relay is a small rectangular box with multiple prongs. You can test it by swapping it with a known good relay of the same type, or by using a multimeter to check for continuity.

Fuel Pump Replacement Cost

The cost of replacing the fuel pump on a 2000 Mitsubishi Mirage varies depending on whether you do it yourself or hire a professional. For a DIY job, the fuel pump assembly itself typically costs between $80 and $150 for a quality aftermarket part. If you go to a shop, parts and labor can run much higher. On average, a professional fuel pump replacement for this vehicle ranges from $222 to over $900, depending on the shop and the specific pump used. The labor is the expensive part because accessing the pump takes time. Doing it yourself can save you a significant amount of money.

Choosing the Right Replacement Fuel Pump

When it's time to replace the fuel pump on your 2000 Mitsubishi Mirage, you need a pump that meets or exceeds the original equipment manufacturer (OEM) specifications. The factory pump is designed to deliver a specific flow rate and pressure. Using a pump that does not match these specs can cause poor performance, rough idle, or even engine damage.

Look for a pump with a flow rate of at least 50 to 60 liters per hour (LPH) and a pressure rating of around 40 to 50 psi. These values are typical for the 2001 Mirage fuel system, which is essentially the same as the 2000 model. The pump should be a direct fit, meaning you do not need to modify any brackets, wiring, or fuel lines. A quality replacement pump will come with the necessary strainer, o-rings, and gaskets for a complete installation.

Brands like Bosch, Delphi, and Airtex are well-known and reliable. However, there is an excellent alternative that offers great value and performance.
