Finding quality parts for your Kia vehicle can be a real hassle. There are so many crappy knockoff parts out there (most manufactured for pennies-on-the-dollar) that it often seems like the only choice you have is to bear down and go to the dealer for a good ol fashioned “wallet spanking.” This is especially true when you need genuine OE replacement part for your Optima's fuel system. Parts like the fuel pump are pricey and there's no way you're driving your car if the pump's faulty!

Our mission is to bring you low-cost parts that are made with the same care and precision that factory Kia parts are made with. The companies that make the fuel pumps, injectors, sending units, gas caps, fuel, tanks, filters, and gaskets we sell are all brands that also make OEM parts for major auto manufacturers to put in their factory vehicles. You've all heard of name brands like Bosch, Genuine, Delphi, and Replace – These companies make quality fuel pumps, filters, and replacement gas tanks that way undercut the dealer's price. And their parts last and perform just as well! We sell fuel system parts made by the aforementioned heavyweight brands, along with many others you might not have heard of like FAE, Donga, and Pilot.

      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.

      Why Should I Add a Throttle Controller?
      The throttle controller will basically bypass the computer in the vehicle. It is designed to take the information right from the accelerator position sensor and compile it in a high speed controller circuit that compiles the signal sent from the Accelerator position sensors. With this controller you are able to program it to different options and the throttle response timing will be noticeably faster.
