A Practical Guide to the 2013-2017 Kia Rio Electric Fuel Pump
Don't let a failing fuel pump leave you stranded; understand your replacement options for your Rio.
- The 2013-2017 Kia Rio has two fuel pumps; this guide covers the electric one in the gas tank.
- Symptoms of failure include engine hesitation, hard starting, stalling, and a whining noise from the rear.
- For reliability, choose a premium aftermarket brand like Bosch or Delphi; US Motor Works is a budget-friendly alternative.
- DIY replacement is possible thanks to an access panel under the rear seat, which avoids dropping the fuel tank.
Is Your Kia Rio's Fuel Pump Failing?
A bad in-tank electric fuel pump will give you clear warning signs. Because it's the first part of the fuel delivery system, any problem here starves the entire engine. If you notice these issues, your pump may be on its way out.
- Engine Hesitation or Sputtering: The car may jerk or sputter when you accelerate, especially when going uphill or carrying a heavy load. This happens because the weak pump can't supply enough fuel when the engine needs it most.
- Difficulty Starting: Your engine might take longer than usual to start, or you may have to crank it several times. A complete failure means the engine will crank but never start.
- Stalling: The engine may stall unexpectedly, either while driving or at idle. This is a serious safety concern.
- Whining Noise from Rear Seat: A loud humming or whining sound coming from the gas tank area is a classic sign of a fuel pump motor working too hard and about to fail.
- Check Engine Light: A failing fuel pump can trigger the check engine light. The most common trouble code is P0087, which means the fuel system pressure is too low.
Choosing the Right Aftermarket Fuel Pump
When replacing the fuel pump on your Rio, you have several aftermarket options. They generally fall into tiers based on quality, reliability, and price. All the brands listed are complete fuel pump module assemblies, which is the recommended way to replace the part.
Tier 1: OE-Quality Replacement
Bosch & Delphi: These brands are major original equipment (OE) suppliers to many car manufacturers. They are known for high-quality engineering, reliability, and long service life. Choosing a Bosch or Delphi pump is the closest you can get to the quality of the original part that came with your car. While they are the most expensive aftermarket options, they provide the most peace of mind.
Tier 2: Value-Focused Replacement
US Motor Works: This brand offers a more budget-friendly option. Reviews suggest they are a solid value, but some users report a shorter lifespan or occasional issues with fitment compared to premium brands. If your budget is tight, US Motor Works is a viable choice, but it may not have the same long-term durability as a Bosch or Delphi unit.
Pro Tip: Replace the Whole Assembly
The fuel pump is sold as a complete module that includes the pump, sending unit (for the fuel gauge), and filter. It is strongly recommended to replace the entire assembly. This ensures all components are new and prevents you from having to do the job twice if an old sensor fails.
Cost of Replacing Your Kia Rio Fuel Pump
The total cost depends on whether you do the job yourself or take it to a shop. Here are some estimated costs:
| Item | Estimated Cost |
|---|---|
| New Aftermarket Fuel Pump | $55 - $111 |
| New OEM Fuel Pump | $350 - $500 |
| Shop Labor | $180 - $350 |
| Total (Shop Repair, Aftermarket Part) | $235 - $461 |
Known Issues: Recalls and Service Bulletins
As of early 2026, there are no specific recalls or Technical Service Bulletins (TSBs) from Kia for widespread failure of the in-tank electric fuel pump on the 2013-2017 Rio. However, a major recall (NHTSA ID: 23V-652000) was issued for a faulty ABS module that could cause a fire, which includes the 2011-2017 Rio. Always check with a dealer to see if your specific vehicle has any open safety recalls.
Frequently Asked Questions (FAQ)
Can I replace the fuel pump myself?
Yes, this is a DIY-feasible job for someone with moderate mechanical skill. The 2013-2017 Kia Rio has an access panel under the rear seat cushion, so you do not need to drop the entire gas tank. However, you are working with gasoline, which is dangerous. You must disconnect the battery, work in a well-ventilated area, and have a fire extinguisher nearby.
My mechanic mentioned a high-pressure fuel pump. Is that the same thing?
No. Your GDI engine has two pumps. This article is about the low-pressure electric pump in the tank. The high-pressure fuel pump is a mechanical pump located on the engine itself. The symptoms can be similar, so a proper diagnosis is important before ordering parts.
Why shouldn't I just buy the cheapest pump I can find?
While very cheap pumps are tempting, they often use lower-quality internal components that can fail prematurely. Replacing a fuel pump is a significant job, and you don't want to do it again in a year. Investing in a quality brand like Bosch or Delphi often saves you money and headaches in the long run.
Do I need to replace my fuel filter at the same time?
Yes. The new fuel pump module assembly will come with a new fuel filter sock (strainer) already part of it. This is one of the main reasons you should always replace the complete module, not just the pump motor itself.
