How much does it cost to replace a fuel sending unit?

The average cost to replace a fuel gauge sender is between $800 and $1,000. The labor costs around $150 to $200, while the parts account for $650 and $800. These replacement costs vary based on what type of car you drive and how difficult the installation is.

Are fuel sending units interchangeable?

We strongly recommend that you DO NOT mix different brands of temperature gauges and senders. Temperature gauges are designed to work with one particular sender. Each sender has an electrical element with specific characteristics.

Is a fuel sending unit the same as a fuel pump?

The fuel sending unit located in the gas tank to measure the fuel tank level. Some sending units are attached to the fuel pump assembly, while others are stand-alone units, but both are made up of the same three components: a float, a metal rod/arm, and a variable resistor.

How long does a fuel sending unit last?

Your vehicle’s fuel pump should last at least 100,000 miles or more. If it doesn’t, or if you’ve exceeded that mileage milestone, you may notice any of the following seven signs.

What can cause a fuel gauge to stop working?

The most common reason a fuel gauge is not working or is inaccurate is due to a bad fuel level sending unit. It can also be caused by bad wirings between the gauge and fuel sender or a blown fuse to the fuel gauge. The fuel gauge itself can also be damaged.

What happens when a fuel sending unit goes bad?

A faulty fuel gauge sender may cause the gauge to suddenly change positions, or give an inaccurate reading. The gauge may appear to be at three quarters, and then only a few minutes later will change to half full, or vice versa the gauge may appear to be full, only to have the gauge climb higher a short while later.

Why do sending units fail?

There are several reasons why a fluid level sending unit can fail. The foremost reason is a lack of proper maintenance. For example, a dirty liquid tank can cause the float to get stuck as debris can get caught between the float and the level tube and prevent freedom of movement.
