Filters contaminants from fuel before it reaches the engine. A clogged fuel filter causes symptoms similar to a failing fuel pump and should be inspected first.

Controls fuel system pressure. A faulty regulator can cause rich or lean running conditions and may mimic fuel pump problems.

Spray fuel into the engine cylinders. Clogged or leaking injectors affect fuel delivery and should be inspected when diagnosing fuel system issues.

Measures fuel level in the tank and is part of the fuel pump module assembly. Often replaced together since the tank must be accessed for both.
