How to Install a Fuel Sender in 5 Steps
Keeping your auto's fuel tank fed with gas is made possible with a fully functional fuel sending unit. If your auto's fuel sender has already exceeded its service life and has failed to transport enough fuel, then better find a replacement right away to avoid impending repair. Here is a quick and easy guide in installing a fuel sending unit.

Preparing for the installation
Dealing with fuel problems needs to be done cautiously because gas is highly flammable. So before installing your fuel sender, be sure to disconnect the negative battery cable first in order to prevent electrical sparks.
Gaining access to the fuel sender
Your car's fuel sender may be located on top of the fuel tank, but it is accessed under the back seat. In other cases, you can detach the stock unit from underneath the trunk's carpet. Once the location is found, you may have noticed that the fuel sender is protected by a cover, which is screwed tightly in place. Simply unbolt the screws to reveal the fuel sender.
Unplugging the wiring harness
The access cover should have been removed by now and the stock fuel sending unit should be right on top. As you can see, the original part has a wiring harness plugged in. This unit sends information to the gas gauge as how much fuel is in the tank. Remove the wiring harness. It will be re-installed later once the stock fuel sender is removed and a new one is placed.
Unscrewing the stock fuel sender unit
Once the wiring harness is removed, detach the stock fuel sender unit's bolts with a screwdriver. In other cases, the fuel sender employs a twist-lock protection that can be removed with a flat head screwdriver. Simply place the tip of the screwdriver in the notch along the fuel sender's outer ring. Rotate it counter-clockwise to loosen and remove the stock part.
Installing the new fuel sender
Once the stock fuel sender is removed, attach a new one, and your car is good to go. Be sure that the fuel sender is plugged in so it will work.
