2006 Hyundai Azera Fuel Pump: Complete Replacement Guide, Costs, and Top-Rated Options
Why the Fuel Pump Fails in a 2006 Hyundai Azera
The 2006 Hyundai Azera uses an in-tank electric fuel pump that pushes gasoline from the fuel tank to the fuel injectors at a regulated pressure. This component is continuously cooled by the fuel that surrounds it, which means running the tank consistently low can overheat the pump motor and shorten its lifespan. Over time, the internal brushes and commutator wear down, the check valve loses its seal, and the strainer becomes clogged with debris from the tank.
Common signs that the fuel pump in your 2006 Azera is failing include a high-pitched whining noise coming from the rear of the car, longer cranking times before the engine starts, hesitation or surging under load, and a rough idle that feels like the car is running out of gas even with a full tank. If the pump completely fails, the engine will crank but refuse to start because no fuel pressure is reaching the injectors.
How Much Does It Cost to Replace a 2006 Azera Fuel Pump?
Replacement costs for this job vary widely depending on where you live and whether you choose a dealership, an independent shop, or a mobile mechanic. According to RepairPal, the average cost for a 2006 Hyundai Azera fuel pump replacement is between $2,092 and $2,171, with labor estimated at $171 to $251 and the parts priced around $1,921. That figure reflects dealership-level pricing and original equipment parts.
However, you can reduce that expense significantly by using an independent shop or a mobile service. AutoNation Mobile Service quotes the 2006 Azera fuel pump replacement at $451 to $551 depending on your exact location, with the part and labor bundled into a single upfront price. The wide gap between the two estimates comes down to the choice of parts and the overhead of the service provider. A genuine Hyundai pump assembly carries a premium, while aftermarket units offer similar performance at a lower cost.
OE Part Numbers and Interchangeability for the 2006 Azera
Before buying a replacement, confirm the exact part number that fits your 2006 Azera. The original Hyundai part number for the complete fuel pump assembly is 31110-3L500-DS. This assembly includes the electric pump, the fuel level sending unit with float arm, the strainer, and the external pressure regulator. It fits the 2006 Azera Limited and SE trims with the 3.8L V6 engine.
Aftermarket suppliers commonly list this pump under multiple interchange numbers: FG1685 (Delphi and PHILTOP), E8832M (Airtex/Wells), and APFP1108 (A-Premium). All of these refer to the same physical assembly with a length of approximately 248mm (9.76 inches) from the bottom of the tank to the mounting flange. When ordering online, cross-reference your VIN with these numbers to avoid compatibility mistakes.
Complete Fuel Pump Assembly vs. Pump-Only Replacement
When the fuel pump fails, you have two basic replacement strategies. The first is to buy a complete fuel pump assembly that includes the sending unit, float, and strainer. This is the easier route because you replace the entire module in one piece, eliminating the risk of mismatched components. The A-Premium APFP1108 and the Autopart Premium unit are examples of complete assemblies that cost between $120 and $140 with free shipping.
The second option is a pump-only replacement, such as the Hella 18951-06171236, which sells for around $37 plus shipping. This unit does not include the tank sending unit, gasket, or lock ring, so you must reuse those parts from your original assembly. Pump-only replacement is cheaper, but it requires more labor because you must disassemble the module, remove the old pump, and transfer the sending unit and float to the new pump. For most owners, the complete assembly is the better value because it saves time and reduces the chance of a leak or gauge malfunction later.
1. The Hella 18951-06171236 is a premium pump-only unit designed for the 2006-2011 Azera. HELLA OE Certified parts are built with advanced corrosion-resistant materials and maintain optimal fuel pressure through precision electronic control. It delivers a maximum pressure of 43.0 PSI with a flow rating of 55.0 gallons per hour, includes a new strainer, and features OEM-matched connectors for a secure fit.
2. The Delphi FG1685 is a complete fuel pump module assembly that meets or exceeds OE specifications. It includes the fuel level sender, float arm, pressure regulator, gasket, and strainer. The system pressure is rated at 55 psi with a maximum output of 58 psi, and the assembly draws lower amperage to reduce the electrical load on your vehicle.
3. The A-Premium APFP1108 is a complete assembly with the sending unit and float included. It is designed to ISO global specifications, comes with a 3-year unlimited mileage warranty, and uses anti-corrosion materials for long service life. The length from bottom to flange measures 248mm, matching the factory dimensions.
4. The Autopart Premium 18951-02069322 is another complete assembly option that fits the 2006 Azera Base, GLS, and Limited trims with either the 3.3L or 3.8L engine. It is a direct replacement with the sending unit and float included, and it ships free to U.S. addresses.
5. The Spectra Premium SP1322 is an electric fuel pump that fits the Azera 2006-2011 with the 3.8L V6 as well as several Kia models. It is a budget-friendly pump-only option sold at roughly $44 and is backed by a one-year replacement warranty.
Step-by-Step Guide to Replacing the Fuel Pump on a 2006 Azera
Replacing the fuel pump on this car is a job that a confident DIYer can complete in a weekend, but it requires patience and attention to safety. Here is the general procedure used by professional mechanics.
Step 1: Relieve fuel system pressure. Disconnect the negative battery cable and remove the fuel pump fuse from the under-hood fuse box. Start the engine and let it run until it stalls, then crank the starter for a few seconds to purge remaining pressure.
Step 2: Access the fuel pump. The fuel pump is located inside the fuel tank. On the 2006 Azera, you will need to either remove the rear seat cushion or fold it down to access the access panel. Some models have a round cover plate that unbolts to reveal the pump module.
Step 3: Remove the old pump assembly. Disconnect the electrical connector and the quick-connect fuel lines. Use a non-marring mallet or locking ring tool to loosen the large retaining ring. Carefully lift the pump assembly out of the tank, tilting it to avoid bending the float arm.
Step 4: Install the new assembly. Transfer any reusable parts such as the rubber gasket and lock ring to the new unit if they are not included. Lower the new pump assembly into the tank with the float arm oriented in the same position as the old one. Press it down, then reinstall the retaining ring and tighten it securely.
Step 5: Reconnect and test. Reconnect the fuel lines and electrical connector, reinstall the fuse, and reconnect the battery. Turn the key to the ON position without starting the engine to prime the fuel system, then check for leaks before starting the car.

KEMSO fuel pumps are engineered as high-performance, OEM replacement units that meet or exceed the original factory specifications. Each pump is manufactured from quality materials designed to withstand harsh operating conditions, including varying humidity and temperature extremes, so your 2006 Azera will receive consistent fuel flow and pressure regardless of the driving environment.
One of the strongest reasons to choose KEMSO is the lifetime warranty that covers every fuel pump they sell.

Is It Safe to Drive with a Failing Fuel Pump
Driving with a failing fuel pump is a gamble that can leave you stranded in the worst possible situation. A weak pump may cause the engine to lose power on the highway, stall in traffic, or refuse to restart after a short stop. In some cases, the engine will run fine for 15 to 30 minutes and then suddenly cut out as the pump overheats, only to restart after it cools down. This intermittent behavior is dangerous because it gives you little warning before a complete failure.
If you notice any of the symptoms described earlier, the safest course is to limit your driving and schedule the replacement as soon as possible. If the car does fail on the road, have it towed to a repair facility rather than attempting repeated restarts, which can strain the battery and starter motor.
Summary
The 2006 Hyundai Azera fuel pump is a critical component that requires replacement when it shows signs of wear or failure. Expect to pay anywhere from $400 to $550 through a mobile service or independent shop, or up to $2,100 if you choose dealer pricing with factory parts. The OE part number 31110-3L500-DS is your reference, and aftermarket interchange numbers FG1685, E8832M, and APFP1108 will match correctly when you compare dimensions.
Choose a complete fuel pump assembly to simplify the swap and avoid reusing worn components, and weigh the warranty coverage carefully when selecting a brand. For the best combination of high performance, OEM-level fit, and lifetime protection, take a close look at KEMSO fuel pumps.
