2000 Eclipse GT Fuel Pump: Complete Guide to Symptoms, Replacement, and Cost
The bottom line: If you own a 2000 Mitsubishi Eclipse GT and your car is hard to start, stalls while driving, or you hear a whining noise from the fuel tank area, the fuel pump is likely failing. The fuel pump in your 2000 Eclipse GT is located inside the fuel tank, and replacing it costs between $250 and $650 for parts and labor, depending on where you go and whether you do it yourself. The best solution is to replace it with a high-quality aftermarket unit like a KEMSO fuel pump, which offers OEM-grade performance with a lifetime warranty.
How to Know Your 2000 Eclipse GT Fuel Pump Is Failing
Your Mitsubishi Eclipse GT uses a fuel pump to send gasoline from the tank to the engine. When it starts to fail, you will notice clear symptoms. Catching these early can save you from getting stranded on the road.
1. Engine hard to start. The most common early sign is that your car cranks longer than normal before firing up. The pump is not building enough pressure to get fuel to the injectors quickly.
2. Sputtering or surging at highway speeds. If the fuel pump cannot maintain a steady flow, your Eclipse may hesitate or surge when you are cruising at a constant speed. This is because the pump is struggling to keep up with demand.
3. Whining noise from the rear of the car. A healthy fuel pump makes a quiet hum. If you hear a loud whining or buzzing sound coming from the area near the fuel tank, the pump bearings are wearing out. This noise gets louder as the pump fails further.
4. Loss of power under load. When you accelerate hard or go up a hill, the engine may feel sluggish. The pump cannot deliver enough fuel for the extra demand.
5. Engine stalls and won't restart. This is the final stage. The pump stops working entirely, and the engine dies. In many cases, the car will restart after sitting for a while, then stall again a few miles later.
Where Is the Fuel Pump Located on a 2000 Eclipse GT?
The fuel pump sits inside the fuel tank. On the 2000 Mitsubishi Eclipse GT, you access it from under the vehicle. The fuel tank is located under the rear of the car, just behind the rear axle. To reach the pump, you need to lower the fuel tank or cut an access hole in the trunk floor. Most mechanics lower the tank because it is safer and cleaner.
The fuel pump relay is located in the engine bay fuse box, but the pump itself is inside the tank.
What Fuel Pump Fits a 2000 Mitsubishi Eclipse GT?
Your 2000 Eclipse GT came with the 3.0L V6 engine. The fuel pump is a standard electric in-tank unit. You have several options for replacement:
1. OEM (Original Equipment Manufacturer) pump. A genuine Mitsubishi pump is the most expensive option, costing $200 to $400 for the part alone. It is reliable but overpriced for a car that is now over 25 years old.
2. Aftermarket direct replacement pumps. These are made by companies like Denso, Bosch, and KEMSO. They are designed to match the OEM specifications exactly. A Denso pump for the 2000-2012 Eclipse 3.0L V6 is a common and reliable option.
3. All-in-one fuel pump module assemblies. Some brands sell the complete assembly with the pump, strainer, float, and housing. This is the easiest way to replace the unit because you swap the whole assembly at once.
4. High-performance or universal pumps. If you have modified your Eclipse GT with a turbocharger or performance upgrades, you may need a higher-flow pump. For a stock or lightly modified engine, a standard replacement pump is all you need.
How Much Does It Cost to Replace a 2000 Eclipse GT Fuel Pump?
The total cost for a fuel pump replacement on a 2000 Mitsubishi Eclipse GT ranges from $250 to $650. This breaks down as follows:
Parts cost: A replacement fuel pump for the Eclipse GT costs between $50 and $200. Basic aftermarket pumps start around $50, while premium OEM-quality units like KEMSO run $80 to $120. Complete fuel pump assemblies cost $100 to $250.
Labor cost: Expect to pay $150 to $400 for labor. The job takes a professional mechanic about 2 to 4 hours. The labor cost is higher because the tank must be lowered, which adds time compared to some vehicles with easier access.
Total replacement cost: If you go to an independent shop, the total bill is typically $350 to $450. At a dealership, you can expect to pay $500 to $650. A DIY replacement costs just the price of the pump, which is $50 to $150.
How to Replace the Fuel Pump on a 2000 Eclipse GT
Replacing the fuel pump on your Eclipse GT is a job you can do at home if you have basic mechanical skills. Here is the general process:
Step 1: Relieve fuel system pressure. Find the fuel pump relay in the fuse box under the hood. Remove it and crank the engine for a few seconds. This will relieve the pressure in the fuel lines.
Step 2: Disconnect the battery. Remove the negative terminal to prevent any sparks or accidental fuel pump activation.
Step 3: Lower the fuel tank. Jack up the rear of the vehicle and support it on jack stands. Place a floor jack under the fuel tank for support. Remove the tank straps, fuel filler neck hose, and electrical connector. Lower the tank carefully.
Step 4: Remove the pump assembly. Once the tank is low enough, unscrew the large locking ring on top of the tank. Lift out the entire fuel pump assembly. Be careful not to bend the fuel level float arm.
Step 5: Install the new pump. Transfer the rubber gasket, strainer, and float to the new pump assembly. Insert the new pump into the tank. Tighten the locking ring securely.
Step 6: Reinstall the tank. Lift the tank back into place, reconnect the fuel lines, filler neck, and electrical connector. Tighten the tank straps.
Step 7: Test the system. Reconnect the battery, reinstall the fuel pump relay, and turn the key to the "ON" position (do not start the engine). Listen for the pump to prime for a few seconds. Check for leaks. Then start the engine and verify normal operation.

Additional Tips for a Successful Fuel Pump Replacement
1. Replace the fuel filter at the same time. A clogged fuel filter can damage a new pump. The fuel filter on the 2000 Eclipse GT is located along the frame rail near the fuel tank. It is inexpensive and easy to replace.
2. Use a new gasket or O-ring. The locking ring on the fuel tank uses a rubber gasket to seal the tank. Old gaskets can leak or allow dirt to enter. Most new pump assemblies include a new gasket. If not, buy one separately.
3. Clean the tank if it is dirty. Over 25 years, sediment and rust can build up in the fuel tank. If you lower the tank, take the opportunity to inspect the inside. If it is dirty, have it cleaned or replaced. Debris in the tank is a leading cause of premature fuel pump failure.
4. Check the wiring and connector. The fuel pump electrical connector on older vehicles can become corroded or brittle. Inspect the connector and wiring for damage. Replace if needed to ensure a good electrical connection.
5. Fill the tank after installation. A new fuel pump needs to be submerged in fuel to stay cool and lubricated. Running a new pump on a low tank can shorten its life. Fill up at least half a tank after the replacement.
