What You'll Learn

Fuel tank replacement cost: $700 to $2,500
Fuel tank replacement costs can vary depending on several factors. The price of a new fuel tank can range from $700 to $2,500, depending on the vehicle's make and model. The cost of labour can also vary depending on location and the extent of the damage. If other components like straps, shields, or the fuel pump need to be replaced, the total cost will increase.
It is important to note that fuel tank replacements are typically covered under mid- to upper-tier extended warranty plans. Factory bumper-to-bumper warranties also cover fuel tanks for three to five years or 36,000 to 60,000 miles, depending on the manufacturer. Some locales mandate a special warranty for the emissions system, including the fuel tank, which can last up to seven years or 70,000 miles.
When replacing a fuel tank, it is recommended to install a brand-new tank. Aftermarket fuel tanks are rare, and used tanks may come with inherent issues.

Warranty coverage: Check if your warranty covers it
Fuel tank replacements are typically covered under mid- and upper-tier extended warranty plans. For example, the Superior plan from Endurance covers your entire fuel system. However, if you want fuel tank coverage from Olive, you'll need to opt for its top-tier Complete Care plan. Generally, warranties only cover bad designs and factory defects. If your fuel tank failed due to water ingress, collision damage, or some other external cause, your claim will likely be denied.
When you buy a new car, it typically comes with a factory warranty provided by the manufacturer. This type of warranty is designed to protect against faulty components, design issues, and other problems that arise through no fault of the owner. Most factory warranties last between three years/36,000 miles and ten years/100,000 miles, depending on the manufacturer. After this warranty expires, you can purchase an extended warranty from the manufacturer or a third-party provider to continue coverage for your vehicle.
Extended warranties can protect your vehicle long after the manufacturer's coverage has ended. However, they usually don't cover pre-existing conditions. Additionally, certain locations mandate that you obtain a special warranty for your emissions system, which includes your fuel tank, with coverage of up to seven years/70,000 miles.
It's important to note that fuel pumps, which are essential for transferring fuel from the tank to the engine, may be covered under extended warranties as well. Mechanical breakdown insurance (MBI) is another option for coverage if your warranty doesn't include the fuel pump. MBI is similar to an extended warranty but is regulated by the insurance commission in your state.
Before opting for fuel tank replacement, it's worth checking if there has been a recall for your fuel tank. In such cases, the manufacturer is typically obligated to replace or repair the faulty parts free of charge.

Fuel pump replacement: $1,000 to $1,200
The fuel pump plays a crucial role in ensuring your engine runs smoothly. It pumps fuel from the gas tank, moving fuel to the engine at the right pressure. When the fuel pump starts to fail, the engine may sputter, misfire, or stop working altogether.
Fuel pumps generally last for over 100,000 miles, and you may never need to replace one even if you own a car for many years. However, they do wear out over time, and you may need to replace it at some point. The cost of replacing a fuel pump ranges from $1,000 to $1,200, with half the cost attributed to parts and the other half to labour.
Labour costs for fuel pump replacement vary between different areas and can influence the overall cost of the replacement. The make and model of your vehicle can also impact the final price. Newer, luxury, and larger vehicles tend to be more expensive to repair.
You can save money by opting for aftermarket parts, which are manufactured by companies other than your car's original maker. These parts are often more affordable than those sourced directly from the dealer. It is recommended to shop around for labour prices, as they can vary significantly between different repair shops.
While it may be tempting to replace the fuel pump yourself, this is a complex and potentially dangerous task that should only be attempted by those with extensive experience working on cars. Fuel tanks contain highly flammable fuel, and even an empty tank can easily catch fire if there is a spark nearby. Therefore, it is generally best to leave this job to professional technicians.

EVAP system issues: Check for leaks and faulty valves
The cost of replacing a fuel tank varies depending on the vehicle model and the extent of the damage. Fuel tanks usually cost between $700 and $2,500 to replace. If other components, such as straps, shields, or the fuel pump, also need to be replaced, the total cost will increase.
Now, onto the EVAP system issues and how they relate to fuel tank replacement. The EVAP (Evaporative Emission Control) system is responsible for regulating fuel vapors and preventing their escape into the atmosphere. When the EVAP system fails, it can cause problems in the vehicle's fuel system and emissions control. An EVAP system leak can lead to increased emissions, negatively impacting the environment, and potentially causing difficulties during emissions tests.
- Strong smell of gasoline: An unusual smell of gasoline around your vehicle may indicate an EVAP system failure or a leak.
- Check Engine Light: The check engine light may illuminate, indicating a potential issue with the vehicle's emissions control system.
- Decreased Fuel Efficiency: You might notice a drop in your vehicle's fuel efficiency, indicating a potential leak in the EVAP system.
- Hissing or Whistling Noises: Unusual noises, like hissing or whistling, near the fuel tank may suggest a leak.
- Hard Starting or Stalling: Difficulty starting the engine or engine stalling could be related to EVAP system issues, particularly a malfunctioning purge valve.
- Visible Smoke or Vapor: Visible smoke or vapor coming from the EVAP system components may indicate a leak.
- Failed Emissions Test: An EVAP system leak can cause your vehicle to fail emissions tests.
When checking for leaks in the EVAP system, a technician will close the purge valve and vent valve and monitor the pressure using the fuel tank pressure sensor. If the pressure drops with both valves closed, there is a leak in the system. If the pressure holds, the system passes and will continue to prevent vapor emissions.
In terms of cost, repairing an EVAP leak can vary depending on the specific issue. A simple fix, such as tightening a loose gas cap, may only cost around $100. Replacing a faulty component like a purge valve or canister might range from $100 to a few hundred dollars. More complex issues or extensive diagnostics may increase the cost.

DIY replacement: Dangerous, leave it to professionals
Replacing a fuel tank is a complex and cumbersome task that requires a lot of steps and precautions. It is not a common occurrence and is usually due to a collision, water getting inside, poor manufacturing, or leaving a car undriven for too long. The cost of replacing a fuel tank varies, ranging from $700 to $2,500, depending on the vehicle. While it may be tempting to attempt a DIY replacement to save money, it is important to leave this task to professionals due to the inherent dangers associated with fuel systems.
One of the biggest challenges in replacing a fuel tank is dealing with the fuel itself. Even when the tank is completely drained, it will still emit fuel fumes, which can be dangerous if inhaled in an enclosed space. These fumes are highly flammable, and even a small spark can cause a fire or explosion. Therefore, it is crucial to work in a well-ventilated area and have a fire extinguisher nearby as a safety precaution.
Another challenge is the physical size and weight of the fuel tank. Fuel tanks are large and cumbersome and can be extremely heavy, making them difficult to handle without assistance. Additionally, the process of replacing a fuel tank involves a lot of steps and technical knowledge. One wrong move can cause damage to the vehicle or injury to oneself. For example, you may need to drop the suspension, remove the driveshaft, unclip all the fuel lines, and deal with various nuts and bolts.
Furthermore, it is important to consider the condition of the other parts in the fuel system. If the breather lines, fuel line clips, fuel tank straps, or bolts are corroded or damaged, they should be replaced with new ones. Using old or rusty parts can compromise the safety of the fuel system and increase the risk of fuel leaks or fires. It is also important to note that fuel tanks are usually still extremely flammable even when removed from the vehicle.
While some people may feel confident in their ability to replace a fuel tank on their own, it is essential to recognize the potential dangers and leave it to professionals who have the necessary training and experience. They will have the knowledge to handle the fuel safely, dispose of it correctly, and ensure that all the parts are in good condition. By leaving it to the professionals, you can have peace of mind that the job will be done safely and correctly, reducing the risk of injury, vehicle damage, or environmental harm.
