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 does a gas tank sending unit work?
The fuel sending unit has a float arm that sits in the liquid gas. When that arm moves up and down, it changes the resistance to ground on a variable resistor. That resistance is then translated and sent through the car’s wiring and electronics to determine where the needle or digital gauge is positioned.
