The fuel sending unit assembly may be a combination of the electric fuel pump, the filter, the strainer, and the electronic device used to measure the amount of fuel in the tank via a float attached to a sensor which sends data to the dash-mounted fuel gauge. The fuel pump by itself is a relatively inexpensive part.
Once fuel arrives at the engine, most modern vehicles distribute the fuel to individual fuel injectors that regulate the amount of fuel used for each engine cycle. How does the fuel injector work? Pressurized fuel is sent into the engine using fuel injectors.
