Anyone knows where the fuel filter located on 2007 Optima 4 Cylinder 2.4L?
I'm ready to change it, but like to know if accessible from under the car,
thnx

The KiaTech web site shows that it's attached to the fuel pump assembly mounted inside the fuel tank, accessed through an inspection plate in the trunk.
The typical installation has a fuel pump suction strainer on the fuel pump assembly which is inside the tank, and a main filter in the fuel pump discharge line before the fuel rail - I'm not familiar with this model and don't know its specific location of the main fuel filter.
Nope it is in the tank, there is no filter in the discharge line. The main filter is wrapped around the tank pump. If you look at the tech bulletins on the KIA tech site you can see the change procedure.
Am I crazy? I looked under the carpet in my trunk and don't see an inspection plate to remove in order to gain access to inside the gas tank. All I saw was solid metal of the trunk floor.
I think you'll find the access cover behind the passenger side rear seat on the trunk floor.
1. Preparation
(1) Open the service cover in trunk.
(2) Disconnect the fuel pump connector
(3) Start the engine and wait until fuel in fuel line is exhausted.
(4) After engine stalls, turn the ignition switch to OFF position.
2. Disconnect the fuel feed quick-connector and the vapor hose.
3. Unscrew the fuel pump locking ring with the special service tool (SST No.: 09310-3K000) and remove the fuel pump assembly.
ok so do we change it or let it be i have been told by the dealership that it is a long life filter and therefore not recommended that it be changed? WHAT the dealership dosent want me to spend hundreds of dollars on a fuel filter replacement!!!! if it should be changed where could i get one and really on a scale of 1-10 what would be the difficulty in changing it myself?
That's got me perplexed. If the dealer says its long life and don't change it, then I'd have to believe them. Why would they tell you this unless it's true? Of course they want to make money on you. In the service manual though it does state to change it. I forget the intervals, but it was more frequently than every 50k miles from what I do remember. I'm at 45k miles now and keep thinking it's overdue. Now that the dealer told you not to change it I'm thinking maybe I should let it slide until 100k miles.
I guess I'll be changing it very shortly as I'm approaching the 37.5k mark. Just want everything to be in accordance with the maintenance schedule so as Kia can't back out of the warranty if a problem arises within the fuel system. Can't believe it will be much of a job.
BELIEVE THE FUEL FILTER IN QUESTION IS ACTUALLY THE EMISSIONS AIR FILTER FOR EVAPORATIVE FUEL EMMISSIONS. BELIEVE IT MOUNTS IN THE DRIVERS REAR INNER FENDER WELL NEAR THE FUEL FILLER NECK. KIA RETAIL IS LIKE $11.00. THE ACTUAL FUEL FILTER IS INTANK WITH THE PUMP AND ARE "LONGLIFE" WE DONT RECOMMEND CHANGING UNLESS THERE IS A FUEL DELIVERY ISSUE OR SOMETHING BAD HAS BEEN PUT IN THE TANK. KPS
i've never changed one on a newer kia and would suggest that unless your car is having a fuel pressure or delivery problem, that it would be a waste of time and money to change it. i'd worry about the evap system air filter before i'd worry about the fuel filter.
There is a "fuel filter" and then the "fuel tank air filter" referenced in my Rio manual as well as my Optima manual.
I spoke with my dealer about the Rio, and he did confirm that the Rio fuel filter is un-serviceable, it's in the tank. Even though many service schedules (my insurance, Gattos, even the Rio Owners manual...lol) lists the "fuel filter" as an item that needs replaced at like 37.5k miles......
I was also able to confirm it by asking around at the various parts stores, all there systems say the part is "un-serviceable" because it's in the tank/pump.
One thing that has me thinking, is perhaps one of the earlier Rio models, or maybe even the Rio5, had the traditional "in line" fuel filter - and they probably just distribute the same manual from year to year Since there's so many features in these owner's guides that list (if equipped) lol.....saves them paper I guess, so they just print out one manual for the full line of cars, but yea, it does add some confusion for us DIYers and such who go looking for parts on our own
Funny thing is, if you Google search for "fuel tank air filter" - most results point to Kia's and Hyundai vehicles.....kinda odd - wonder if they are the only ones that use them? Or if they are the only ones that refer to it as that part? As far as I understand, the "fuel tank air filter" is the charcoal filter/cannister between the tank and the filler nozzle, I guess to filter the gasoline fumes from going into the environment
And my dealer did confirm that the fuel tank air filter is serviceable, generally at 30, 60 and 90k...
I noticed in my service manual that there are replacement intervals for the fuel filter (the one inside the fuel tank). On a recent service visit at my local Kia dealer, I asked what they charged to replace the fuel filter and the response was "It doesn't get replaced. It lasts the life of the car." I was totally confused since that's not what my owners manual stated at all.
It's not uncommon for aftermarket stores not to have some specific components for Kia/Hyundai, or any make for that matter as you'll always find dealer only parts.
I believe this is the filter that they want you to change in the owners manual for warranty purposes for the 2008 Optima.
How do you get to this to change it? Do you get at it from the screws on the fuel filler neck where the nozzle goes in to refuel? There are 4 that I think hold the filler neck in place but I cannot see how that would allow you access. I have looked underneath the car and I see no access to it as it runs down behind the wheel well through a small gap where you really cannot get a hand up inside. . The filler pipe from there then heads over to the fuel tank and it looks like it is wrapped in protective rubber maybe once it bends and heads over to the gas tank. . There is also no access to it from the trunk that I could see.
I'm puzzled at how you acess this. Can this filter also be purchased from a do it all auto parts dealer or do you have to get it from KIA? I had a hard time locating an air filter and cabin filter until I went to I beleive it was an AutoZone.
IF I'm wrong please let me know. I would hope the filter they want you to change is not down in the fuel tank. That would make me think I really made a bad purchase when I bought this vehicle as I would consider it a bad design to not have an easily acessible filter that needs to be changed every 30,000 miles and have it be in the fuel tank which sounds like a real strange design. Of course I'm not that familiar with the car but that is the way I look at it as most designs have an easy to change in line filter somewhere between the gas tank and the engine.

It just depends on the model of car. Some cars I've owned, the fuel filter was attached to the firewall, wedged behind the engine. Not easily reachable, especially if you have short arms like me. Then other vehicles I've owned, the filter was located underneath the car along one side, so it was really easy to see and remove. Now I have this Optima, with the fuel filter located inside the gas tank. I located the inspection plate, removed it, then disconnected the appropriate connections. It's actually not hard at all. Fold your rear seat down and access it from the right rear passenger door rather than through the trunk. Much easier that way.
The $9.00 fuel air filter, rectangular plastic box, is located on the filler tube. Remove the left rear wheel, undo the plugs, screws on the plastic inner fender wheel and peel back. I removed maybe 3/4's of the fasteners, then pulled the inner shield back and held it with a bungee cord. There are 3 10mm bolts that retains the box to the tube, so remove them and loosen the spring clip with plies and the box can be removed. The inner, upper bolt is tough as you need an exact length 10mm socket too long and you can't obtain access, too short and the ratchet hits the box.
Good luck.
There is a fuel filter in the tank it is a replaceable part it is available from the dealer for around $30. You access it thru the cabin, tilt the back seat down and lift the carpet you'll notice a large body grommet the access panel is under there.
It is to be replaced according with the service schedule at 60,000kms.
I just replaced the tank filter on a 2005 optima, it is relatively easy but it leaks petrol everywhere which means no smoking and the cabin will have a faint petrol smell for a day or so.
I cut the old filter open to inspect the filter media and it was about 75% blocked, so I think it could safely run another 15,000kms but it is not a part that should be left in for the life of the vehicle. I estimate it would be totally blocked before 100,000kms.
I've heard many references to a "charcoal canister" associated with the fuel delivery. From what I understand it sits between the filler nozzle/neck and the tank, to block/filter gas vapors from getting into the atmosphere.
Is this "charcoal cannister" what KIA/Hyundai refers to as the "fuel tank air filter"?
Funny, if you Google search for "fuel tank air filter" the only results you will find are Hyundai and Kia.....which has me thinking it may be the equivalent to that of the "charcoal cannister" that other makers label it as?
Interesting to note, I now have an 08 Optima (posted previously regarding my Rio) and when I was at the dealer I picked up their Scheduled Maintenance Guide. They charge 89.95 to replace In tank Fuel Filter, and 79.95 to replace the external Fuel Filter from their price list, but it's nowhere listed on their "Maintenance Schedule" when to replace it....unless it's one of those things hidden under "Multi Point Inspection" - so they replace it (or don't..) and charge you for it before telling you.
Looking at http://www.kiatechinfo.com there is a filter that is part of the Fuel Pump located with the fuel tank. This is accessible in a panel underneath the trunk carpet.
So you could replace the filter that's attached to the fuel pump, but I would assume this is part of the fuel pump and designed to last the life of the car.
However they recommend an inspection at 30,000 miles of the "Fuel Filter" and the "Fuel Tank air filter (CCV Filter)" (part C in this photo). The Fuel Tank filter is part of the emissions system and is located behind the rear left wheel house inner cover. The only other Fuel Filter I can find is the one in the fuel pump itself.
I would imagine these are not that these are that hard to replace just a pain to get to. However the fuel pump does require a "special tool" for taking off locking ring.
