2016 Kia Forte Fuel Pump: What Every Owner Must Know Before Buying a Replacement

If you own a 2016 Kia Forte and your fuel pump is showing signs of failure, you need to replace it quickly. The 2016 Kia Forte uses two different fuel pumps: a low-pressure in-tank pump (part of the fuel pump assembly inside the gas tank) and a high-pressure direct injection pump (mounted on the engine) for the 1.6L turbocharged models. The most common failure point for the 1.6L engine is the high-pressure fuel pump (part number 35320-2B140 or 35320-2B220), which is responsible for delivering fuel at extremely high pressure to the injectors. Replacing this pump early can save you from being stranded, avoid costly engine damage, and keep your car running smoothly. The total cost of a professional replacement ranges from $400 to $800, but you can do it yourself for around $100 to $200 in parts if you choose a quality aftermarket pump .

Understanding the 2016 Kia Forte Fuel Pump System

The 2016 Kia Forte comes in several trims and engine options. The most common engine is the 1.6L four-cylinder, which uses a direct injection fuel system. Direct injection systems require a high-pressure fuel pump that can generate pressures well over 1,000 psi. This pump is mechanically driven by the engine’s camshaft and is located on the engine itself, not inside the fuel tank .

The other pump is the low-pressure in-tank fuel pump (part number 31110-A7000-DS), which sits inside the fuel tank and sends fuel to the high-pressure pump. This pump operates at a lower pressure, typically around 50-60 psi. Both pumps must work together for the engine to run properly. If either fails, your car will exhibit symptoms such as hard starting, stalling, hesitation during acceleration, or a whining noise from the fuel tank area .

Key Part Numbers for the 2016 Kia Forte Fuel Pump

When shopping for a replacement fuel pump for your 2016 Kia Forte, knowing the correct part number is essential. Here are the most common OEM and aftermarket part numbers:

  • High-Pressure Fuel Pump (1.6L engine): OEM part number 35320-2B140 or 35320-2B220. These pumps are used on the 1.6L direct injection engines found in the 2016 Kia Forte Koup SX, Forte5 SX, and Soul Base models. The part number 35320-2B220 is a direct replacement for 35320-2B140 and 35320-2B130 .
  • In-Tank Fuel Pump Assembly (1.6L engine): OEM part number 31110-A7000-DS. This is the complete fuel pump module that sits inside the gas tank, including the fuel level sender and strainer .
  • Aftermarket Interchange Numbers: For high-pressure pumps, look for numbers like FI1549, HP16422, or HDI012 (Herko brand). For in-tank pumps, the Carter P90008 or Beck/Arnley 152-0956 are common replacements .

Symptoms of a Failing Fuel Pump in a 2016 Kia Forte

Recognizing the early signs of fuel pump failure can save you from a breakdown. Here are the most common symptoms:

  1. Hard Starting: If your engine cranks but takes longer than usual to start, or requires multiple attempts, the fuel pump may not be building enough pressure. This is especially common with the high-pressure direct injection pump .
  2. Engine Sputtering or Hesitation at High Speeds: A failing fuel pump cannot deliver a consistent fuel supply, causing the engine to sputter, lose power, or hesitate when you press the accelerator. This symptom is often worse under load, such as when merging onto a highway .
  3. Stalling While Driving: If the pump stops working entirely, the engine will stall. This is dangerous, especially if it happens in traffic. A sudden stall is a sure sign that the pump needs immediate replacement .
  4. Whining Noise from the Fuel Tank: A healthy fuel pump operates quietly. If you hear a loud whining or humming sound coming from the rear of the car (near the gas tank), the pump is likely failing. This noise is caused by worn bearings or a damaged motor .
  5. Check Engine Light: The engine control module will detect low fuel pressure or a pump malfunction and trigger the check engine light. Common diagnostic trouble codes include P0087 (Fuel Rail/System Pressure Too Low) and P0191 (Fuel Rail Pressure Sensor Circuit Range/Performance) .

How to Diagnose a Bad Fuel Pump

Before buying a new pump, you should confirm that the pump is indeed the problem. Here is a simple diagnostic process:

  • Listen for the Pump: Have someone turn the key to the "ON" position (but do not start the engine). You should hear a brief whirring sound from the fuel tank area. If you hear nothing or a loud grinding noise, the pump is likely bad .
  • Check Fuel Pressure: Use a fuel pressure gauge to test the pressure at the fuel rail. For the 1.6L direct injection engine, the low-pressure side should be around 50-60 psi, and the high-pressure side can exceed 1,000 psi. If the pressure is low, replace the pump .
  • Inspect the Fuel Filter: A clogged fuel filter can mimic a failing pump. Replace the fuel filter first if it has been more than 30,000 miles since the last change. If the problem persists, the pump is the culprit .

Why You Should Not Ignore a Bad Fuel Pump

Driving with a failing fuel pump is risky. A sudden stall can cause a serious accident, especially on a highway or during a left turn. Additionally, a bad pump can damage other components. Low fuel pressure can cause the engine to run lean, which can lead to overheating and damage to the catalytic converter, oxygen sensors, and even the engine itself. Replacing the pump early is much cheaper than repairing the damage caused by running the engine with insufficient fuel .

How to Replace the Fuel Pump on a 2016 Kia Forte

Replacing the fuel pump is a job that many DIYers can handle. However, it requires caution because you are working with gasoline. Here is a step-by-step overview:

  1. Relieve Fuel System Pressure: Locate the fuel pump fuse or relay in the fuse box and remove it. Start the engine and let it run until it stalls. This relieves pressure in the fuel lines .
  2. Disconnect the Battery: Disconnect the negative battery terminal to prevent any electrical sparks .
  3. Access the Pump: For the in-tank pump, you will need to lower the fuel tank or remove the rear seat to access the pump access panel. For the high-pressure pump, it is located on the engine, usually near the intake manifold. You may need to remove the engine cover and intake parts to reach it .
  4. Remove the Old Pump: Disconnect the fuel lines, electrical connector, and mounting bolts. Carefully remove the old pump. Be careful not to spill fuel .
  5. Install the New Pump: Install the new pump in the reverse order. Use new gaskets and O-rings that come with the pump. Tighten the mounting bolts to the manufacturer's torque specifications .
  6. Prime the System: After installation, turn the key to the "ON" position for 5 seconds, then turn it off. Repeat this a few times to allow the pump to build pressure. Then start the engine and check for leaks .

Tips to Extend the Life of Your New Fuel Pump

Once you have installed a new fuel pump, following these simple practices will help it last as long as possible:

  • Never run the tank below a quarter full. The fuel in the tank helps cool and lubricate the pump. Running on low fuel causes the pump to run hot, which accelerates wear. Make it a habit to refill when the gauge hits a quarter tank .
  • Use quality fuel from reputable stations. Poor-quality fuel contains more contaminants and water, which can damage the pump. Busy stations with high turnover usually have cleaner fuel .
  • Replace the fuel filter regularly. A clogged fuel filter forces the pump to work harder. Follow the manufacturer's recommended interval, which is typically every 30,000 to 60,000 miles .
  • Address check engine lights promptly. If your car stores a fuel system fault code, have it diagnosed immediately. Early detection can prevent a small problem from becoming a major repair .

Final Thoughts

Replacing the fuel pump on your 2016 Kia Forte is a necessary maintenance task that can prevent unexpected breakdowns and costly repairs. The key is to act quickly when you notice the symptoms: hard starting, sputtering, stalling, or a whining noise from the fuel tank. Diagnose the problem with a fuel pressure test, and if the pump is bad, replace it with a high-quality aftermarket unit. Do not gamble with cheap, no-name pumps that could fail within months.
