How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for a fuel filler neck replacement and how much do those parts cost?

Replacing a fuel filler neck might sound like a simple process, but it requires specialized tools and knowledge to complete the process. But luckily, if your fuel filler neck is damaged or broken, it’s generally the only part that needs to be replaced, which can help to reduce your costs. 
On top of the part itself, some tools and equipment are also required, including: 
  • Jack stands or other means of lifting the vehicle
  • Soldering equipment
  • Protective gear
If you’re having your fuel neck replaced at a mechanic, they’ll already have the equipment, so you’ll only be responsible for covering the costs of the part and labor. A replacement fuel filler neck typically costs between $157.31 and $192.27.
We recommend purchasing a fuel filler neck at local auto parts stores like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts, or online retailers like Amazon and RockAuto. The three brands we recommend are brands Spectra Premium, Dorman, and ACDelco for fuel filler neck components. Keep in mind that, like price, recommended brands may also vary depending on your vehicle’s specific year, make, and model.
The short answer is no. While silicone has many uses, it’s a porous material that can’t withstand gasoline and oil, so it shouldn’t be used for a fuel filler neck. Instead, a rubber house may be used, offering excellent fuel resistance.
When it comes to replacing your fuel filler neck, OEM parts are generally recommended. Because they are designed specifically for your vehicle make and model, they have the perfect fitment and mount, preventing fuel leaks and other malfunctions. Although they tend to cost more than aftermarket parts, they’ll cause fewer problems in the long run.

How will a mechanic replace my fuel filler neck?

Here are the basic steps that a mechanic may take to perform a fuel filler neck replacement:
  1. The mechanic may raise the vehicle on jack stands. Then, they will likely remove a wheel to access the fuel filler neck.
  2. The inner fender must be temporarily removed to allow the mechanic to access the faulty filler neck.
  3. The mechanic will take out the defective filler neck. Then, the new part will be installed, and the inner fender replaced.
  4. Now, the vehicle can be taken off the jack stands and taken for a test drive to ensure the problem is resolved.

What happens if I don’t replace my fuel filler neck?

This repair is critical, as a faulty fuel filler neck is a fire hazard. It creates a pool of flammable liquid underneath and inside your vehicle. Not only is a faulty part dangerous, but it can contribute to poor fuel economy. If you notice puddles of gas or decreased mileage, do not hesitate to book a fuel filler neck replacement.

What is a fuel filler neck?

The fuel filler neck is a solid piece of formed steel that joins the fuel filler inlet (where the gas cap attaches to) and the rubber fuel fill hose to the gas tank in the fuel system. It is sealed using a steel hose clamp to prevent any fuel leakage. Inside the fuel tank filler neck, you’ll find a one-way valve allowing fuel through but preventing other objects from entering the tank, such as a siphon hose. 
Over time, the fuel filler neck collects debris and dirt and can start to rust, forming leaks. The rubber hose can also become weather-cracked, causing further leakage. When this happens, you’ll need a replacement neck installed. 

How do I know if my fluid filler neck needs replacing?

Because the fuel filler neck is located in an inaccessible area, it can be hard to determine when it needs replacing. As such, there are some common symptoms to watch out for if it’s time to replace it:
  • Smell fuel vapors
  • Leaking fuel or other chemicals 
  • Low gas mileage
  • Below-average performance
  • Check engine light is on

How often should you change your fuel filler neck?

The fuel filler neck on a vehicle is designed to last a lifetime, so there’s no set replacement interval. However, with its metal construction, rust is one of the most common causes of a faulty fuel filler neck that needs to be replaced.
When you take your car for
regular maintenance
, ask your mechanic to check the fuel filler neck. Problems are easier to fix when caught early.

Can I replace the fuel filler neck myself?

Even if you’re car-savvy and have experience under the hood, replacing the fuel filler neck is a complicated process that takes time and a fair bit of equipment. As such, it’s not a great DIY project: calling your local auto body repair shop and leaving it to a professional mechanic is recommended.

FAQs

The fuel filler neck is the gateway to your gas tank, and leakage can be hazardous. Liquid fuel doesn’t burn, but the fuel vapors are highly flammable. If the fuel filler neck leaks, you risk fuel vapors igniting if a spark is caused by rocks thrown into the wheel well or under the vehicle.
Although you can drive with a bad fuel filler neck temporarily, it’s not recommended. A damaged neck not only causes issues with the vehicle’s emissions but can also become a serious safety hazard if the fuel neck leaks. If you notice any signs of a faulty fuel filler neck, have your vehicle checked out by a mechanic as soon as possible.
The total cost to replace a fuel filler neck averages $529, but the exact cost will depend on which part you buy and your vehicle’s make and model. However, if your car is still under warranty, the replacement cost may be covered.
