The fuel filter location varies with engine size on the Kia Optima. The 1.5-, i.half-dozen- and ii.4-liter engines have the fuel filter located under the car in the forepart left corner of the fuel tank. The 1.8-liter engine has the fuel filter located on the driver's side firewall. All the filters have the same replacement procedure. There are actually two filters on the Kia Optima. A filter called a strainer is attached to the intake side of the fuel pump inside the fuel tank.

Step i

Lift the hood and remove the cap on the fuse and relay box located on the commuter's side fenderwell. Await at the bottom of the cap for the location of the fuel pump relay inside the box. Pull the fuel pump relay out and lay information technology sideways in the box.

Step 2

Start the engine. It is not likely to start and even if it does it volition only run for a 2d since the fuel pump relay has been removed, which disabled the fuel pump. This process volition drop the fuel pressure in the fuel line. Raise the rear of the vehicle with the floor jack and back up it by the frame with the jack stands. This is for engines ane.5, 1.6 and two.4.

Footstep 3

Remove the fuel lines on both ends of the fuel filter. Use the scribe--a long pointy needle--to elevator the white retainer straight up located in the center of the connector. This releases the fuel line from the fuel pump. Practise the same to the other side of the fuel pump.

Footstep 4

Remove the bolt in the center of the fuel pump retainer bracket using a 10 mm socket. Pull the fuel pump out of the bracket.

Step 5

Insert the new fuel pump into the retainer subclass. Brand sure that the inlet side faces the fuel line to the fuel tank and the outlet toward the fuel line to the engine. Install the fuel pump and bracket and tighten the bolt.

Identify a white servant clip that came with the filter into the holes in each of the connectors. Just push it in enough to snap the lesser ends of the clip in place. The clip should now be standing straight upwardly with just the bottom tips in the connectors. Push each of the fuel lines into the filter one at a time. Holding the fuel line tightly into the filter, push the white retainer clip down to lock the fuel filter and fuel line together. Lower the car and supplant the fuel pump relay. Start the motorcar and check for leaks.
