Where is my fuel filter located on my vehicle? The car is showing signs of sluggishness up hills and when I speed up rapidly; it may be misfiring caused by a fuel injector, but I would like to try changing the fuel filter first. I have a 2.4 liter 16v DOHC four cylinder engine and cannot find the fuel filter; normally they are located near the fuel tank and did not see it. What am I missing? Your help would be greatly appreciated. Thanks.

Yeah, it should be near fuel tank if it is an in-line filter which is what it is listed as. Although, earlier models of the Optima had the fuel filter in the tank with the pump and sender assembly. So I would not be surprised if they have it listed wrong. May want to check there for the fuel filter. Try removing rear seat cushion to see if you have an access panel. Should be able to see sender unit from there to locate filter if it is in the fuel tank.

Thanks. The access hole is in the trunk just behind the seats you do not need to remove the seat to access it; it is in the middle with a plastic cover. Thanks again, as soon as I figure out how to open the sending unit cover I will let you know how it runs if you are interested; I am sure it just unscrews. Anyway thanks again.

The fuel filter is part of the in-tank fuel pump in your vehicle (#2), you will need to remove the fuel tank to get to it.
Check the guide below on fuel tank removal as well as the diagrams for your specific vehicle and get back to us if you need anything else.

Hi Toni,

I am going to assume you have a 2.7L engine. If so, the reason you cannot find the filter is because it is part of the fuel sending unit and is inside of tank.

If you have a 2.4L it is on the left hand side of the fuel tank.

If it is a 2.7L you would only change the filter if there is an issue and you need to replace the fuel module. I also attached the procedure if that is what you want to do. Thanks

Four cylinder two wheel drive automatic.

I am having a difficult time locating to the fuel filter on a my car it has a 2.4 liter engine. Could you please help me locate it and give me any tips you could to assist me in changing it? I was told it is inside the gas tank and it may or may not have an access panel. Is there a gasket I will need or is is even in the tank?

It is under vehicle mounted in the fuel rail line (pictured below). Some cars have them and some don't depending on production date.


https://www.2carpros.com/forum/automotive_pictures/261618_1_69.jpg



INSTALLATION:
Install the filter in the mounting bracket.
Connect the fuel lines to the filter.
Install the bracket nuts and tighten to 9.5 ft. lbs. (13 Nm) for 1.5L, 1.6L, 1.8L and 2.0L engines. For 2.4L engines, torque the nuts to 18-25 ft. lbs. (25-35 Nm).
Connect the negative battery cable.
Run the engine and check for any fuel leaks.

This fuel filter location is in the rear of the car near the fuel tank on the drivers side.

Here is a guide to help you get the job done:

This guide will show you how to raise the car up safely.

Some Kia's do not have an external fuel filter the filter is in the tank, check out these diagrams (below) Its considered a lifetime filter.

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

That is because the filter is part of the fuel pump inside the tank. The only time it is replaced is when the pump is removed for other reasons. Otherwise it just stays in there.

I attached the info on this. Let us know if you have more questions. Thanks

Speeding up and about 60 mph it wouldn't advance even though I was stepping on the accelerator. All of a sudden it started running fine and advanced to 70 mph. Hasn't done it again. Could this possibly be the fuel filter?

Hi and thanks for using 2CarPros.

The fuel filter is located underneath the chassis on the left hand side of the fuel tank.

See picture 1

Here is a link that shows in general how one is replaced:

https://www.2carpros.com/articles/how-to-change-a-fuel-filter

Here are the directions specific to your vehicle for replacement:

___________________________________

FUEL FILTER REPLACEMENT

1. Reduce the internal pressure of the fuel lines and hoses and perform the following operations.
- Disconnect the fuel pump harness connector in the trunk room.
- Start the engine and, after it stops, turn the ignition switch to OFF.
- Disconnect the battery negative (-) terminal.
- Connect the fuel pump harness connector.

2. Remove the two fitting nuts while holding the fuel filter nuts securely.

See picture 1

3. Remove the fuel filter mounting bolts, and then remove the fuel filter from the fuel filter clamp.

Tightening torque
Fuel filter fitting nut : 25 - 35 Nm (250 - 350 kg.cm, 18 - 25 lb.ft)

____________________________________

Let me know if this helps or if you have other questions.

Take care,
Joe
