The fuel filter is inside the tank in a canister that holds the fuel pump. Contrary to popular belief the 2003 Kia Sorento has a fuel filter that you can get at your dealership. (I purchased one today at my dealer for appox $46 vs the $320 for the whole new pump). It was the only model year that had a replaceable filter.
To find the filter:
Open back passenger door and pull bottom of the seat forward. You will see a square metal plate that has a wiring harness attach. Use a Phillips screwdriver and remove the 4 screws. Unhook the gas lines, and 3 electrical plugins. Unscrew the 4 bolts holding the pump canister and slowly remove the canister from the tank pulling up. Inside this canister us the pump and the filter etc.
You will need to get a diagram from there to remove and replace unless mechanically inclined, although it is fairly simple to do.

Fuel filter is in the tank & comes as part of the fuel pump. Pump & filter are changed as a complete assembly.

Follow the (usually steel) fuel lines from the engine bay underneath the vehicle all the way back to the fuel tank. fuel lines may resemble brake lines, they usually look very much alike. Find your fuel rail, it connects to fuel injectors, and then follow it to find the fuel lines that go to the fuel tank.

You may have to remove plastic covers from underneath the vehicle, one kia I worked on the fuel filter was halfway up the side of the fuel tank and we had to remove the whole undercarriage cover from underneath the vehicle to follow the fuel lines to it.

I assume you have the new fuel filter, so you know what you are looking for, if you don't it looks like a can with a fuel line coming out of either side of it. Similar to what an engine oil filter looks like, usually quite a bit smaller though.

Hope this helps :)

2011 KIA Sorrento 2.4 were is the fuel pressure regulator located. put on adjustable fuel reg .need to disconnect stock one


fuel pressure regulators are normally located in the fuel manifold. They are either vacuum controlled or electronic controlled to maintain the right fuel pressure for engine requirements and to shut off the fuel pump when the ignition is turned off
If your manually adjusted unit will not do all that then you are asking for fault codes to appear and all sorts of problems to occur

Fuel filter location


It is located under rear seat access panel, but is inside fuel tank(Surrounding pump).
You need to be pretty confident to tackle this job, as it requires removal of lots of intricate parts.
