    • Replacement Fuel System Parts
      Does My Vehicle Have a Mechanical or Electric Fuel Pump?
      From the earliest days of the automobile, fuel pumps have existed to draw fuel out of the fuel tank and move it into your engine's combustion area. (A note for the purists: some very early cars, like the Ford Model T, used "gravity feed", which required the fuel tank to be mounted higher than the engine. These cars could only climb steep hills by ascending them in reverse!)

      How To Replace An In-Tank Fuel Sending Unit
      A Fuel tank sending unit is a term for the mechanical assembly inside your fuel tank which measures the level of liquid in the tank, then reports its findings to the fuel gauge on your instrument cluster. All sending units contain a "float" piece which does just what it describes - floats atop the surface of the fuel. Many automakers design the float piece as an attachment on a hinged arm that pivots as the level in the tank rises or drops. Others design the float piece as a cylinder that rides up and down around a metal shaft.

      How To Replace Fuel Injectors
      Fuel injectors spray fuel directly into your engine’s cylinders during the intake stroke when a piston moves down to allow air and fuel to fill the cylinder chamber. When injectors are malfunctioning, leaking, or have failed completely, they will cause rough engine performance, poor idle, reduced power and economy, and exhaust that’s rich enough in unburned fuel to damage expensive exhaust parts such as oxygen sensors and catalytic converters.
