What parts do I need for a fuel gauge sender replacement and how much do those parts cost?
If your fuel sender unit is faulty, you can take it to a mechanic to replace it or do it yourself. Because the fuel gauge sender is a single part, it’s usually the only part you’ll need to replace if it breaks.
The average cost for parts to replace a fuel gauge sender is between $130.05 and $158.94. Remember, you’ll have to pay labor fees on top of that.
If you’re changing your fuel gauge sender at home, you’ll also need some basic tools, including:
- Flathead screwdriver
- Phillips head screwdriver
- Hammer
- Open-end wrenches
If your fuel gauge sender is faulty and your vehicle is still under warranty, contact your local dealership to see if it’s covered. If you do need to purchase the part for your replacement, we recommend going to your local auto parts stores like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts, as well as online retailers like Amazon and RockAuto. Three trusted brands that we recommend are ACDelco, Spectra Premium, and Delphi. However, like price, recommended brands may also vary depending on your vehicle’s specific year, make, and model.
What happens when a fuel-sending unit goes bad?
Inaccurate fuel gauge readings are the most common sign of a malfunctioning fuel level sending unit. It may be stuck on full or empty or give incorrect and inconsistent readings.
Should I buy an OEM or aftermarket fuel gauge sender?
Purchasing an OEM part is recommended if you’re replacing your fuel gauge sending unit. Although aftermarket parts may be cheaper, not all sending units are calibrated the same, and some aftermarket sending units won’t work with many original fuel gauges. Aftermarket fuel gauge senders are designed for aftermarket gauges and operate between 240 ohms (closed) and 33 ohms (open).
Where can I buy a new fuel gauge sender?
Fuel gauge senders are widely available through auto part shops like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts or online through sites like Amazon and RockAuto. You may also be able to buy new OEM parts through your dealership.
Where can I get my fuel gauge sender replaced?
If you’re car-savvy and want to attempt to replace your fuel gauge sender at home, it’s a great way to save money. But if you’re not keen on getting your hands dirty, finding an auto repair shop to do the job can be tricky, especially if you don’t have a trusted mechanic in your area. Luckily, Jerry's

How will a mechanic replace my fuel gauge sender?
A mechanic will usually complete the following steps when performing a fuel gauge sender replacement:
- Release the fuel tank pressure following your owner’s manual instructions
- Disconnect the fuel lines and electrical connectors from the fuel gauge sender
- Clean the area to ensure it is free of any contaminants
- Use a non-ferrous tool to remove the retaining ring (if required)
- Remove the old fuel gauge sender with the gasket/O-ring from the tank
- Install the new fuel sending unit
- Reinstall the retaining ring (if removed before)
- Reconnect all electrical connections and put the fuel lines back in place
- Check for leaks
What happens if I don’t replace my fuel gauge sender?
While you won’t experience significant damage to your vehicle if your fuel gauge sender is defective, it can become a huge inconvenience. You could end up stranded on the road without expecting it because your fuel gauge gave a false reading.
Replace your fuel gauge sender as soon as possible if it has failed or is only operating occasionally.
What is a fuel gauge sender?
The fuel gauge sender, also referred to as the fuel sending unit, is a component found in the gas tank of most vehicles that’s responsible for sending the signal that controls the fuel level gauge on the car’s instrument cluster.
It consists of an arm, float, and a resistor that changes based on the float's position. The sender float floats on the top of the fuel inside of the gas tank. As the fuel level drops, the position of the arm and float changes and moves the resistor to control what appears on the display.
During a replacement of a fuel gauge sender, a mechanic will replace your defective one with a new one that operates properly.
Though the fuel gauge sender is a relatively simple component in your car’s fuel tank, the reading on your fuel gauge can become inaccurate if it's malfunctioning for any reason.
How do I know if my fuel gauge sender needs replacing?
Here are the most common symptoms of a bad fuel gauge sender:
- Your fuel gauge only ever reads empty
- Your fuel gauge only ever reads full
- Your fuel gauge reads inaccurately or inconsistently
Remember that if you’re receiving inaccurate readings, it’s not always because the sending unit is faulty. A bad connection with the signal wire from the fuel gauge sender or a poor grounding wire can also lead to inaccurate readings. You might also have a blown fuel gauge fuse.
Troubleshooting this issue is often a professional job, but if you have a multimeter at home, you can use it to self-test the voltage of the fuel gauge wire—the multimeter should be set to 20V DC. If the fuel gauge is not receiving 12 volts, check for signs of damage or a loose connection.
How often should you change your fuel gauge sender?
For drivers looking to
save money on car expenses
, you shouldn’t have to worry about replacing your fuel gauge sender after a set interval. They’re designed to last for the vehicle's lifespan, but in some cases, they may become faulty or fail. However, some vehicles have standalone senders, while others have it built into their fuel pump assembly. If you have a standalone sender, replacing it is often easier and cheaper.
If you suspect a problem with your fuel gauge sender, have a mechanic look at it when your car is serviced.
Can I replace the fuel gauge sender myself?
If you’re car-savvy and have experience working with electrical and fuel parts in a car and want a DIY project, you might be able to replace the fuel gauge sender yourself. However, fuel gauge work is slightly complicated and time-consuming, so if you’re not confident working on cars, it’s probably better left to a professional mechanic.
FAQs
Why is my fuel gauge sending unit not reading correctly?
Inaccurate readings on the gas gauge sender are usually due to a few issues:
- The float has separated from the metal rod (arm) and isn't giving feedback about the fuel level
- The variable resistor is faulty and malfunctioning
- The fuel system’s wires have corroded and aren’t providing information
How much does it cost to replace the fuel sending unit?
The average cost to replace a fuel gauge sending unit is $396. You’ll pay around $169 for parts and about $227 for labor—but these costs can vary based on the make and model of your vehicle.
What causes the fuel sending unit to fail?
Incompatible fuel additives are the most common reason for a faulty fuel gauge sender. Adidtie can cause the float in the unit to not float properly, causing incorrect readings. The unit can also fail due to physical damage.
