Subaru fuel filter changes should be the same across most platforms / models up until 04 STI / WRX or 05 STI / WRX (or similar) where it moved to the fuel tank. What you will need:

• Phillips Screwdriver - for the hose clamps
• Eye Protection - To keep petrol from getting in your eyes in case you flick a petrol line while removing it.
• Rags - To catch any petrol that will dribble out of a hose after you remove it
• Fuel Filter - From your local Automotive outlet.

You're best to change your fuel filter after the car has sat overnight. Reason being, the motor is cold and all the pressure in the fuel system has dissipated. Another method of doing this is to pull the fuse for the fuel pump, run the car till it stalls then remove the filter. Either method should work without any issues.

Ensure that you wear eye protection before you commence, to avoid petrol in the eye.

Locate the fuel filter and undo the two lines that run over the filter from the plastic clip. With a phillips screw driver, loosen both hose clamps and slide the clamps about as far down the hose as you can. This will give you a good spot to grip the hose and the clamp won't get stuck at the bump in the filters petrol line.

Next, undo the clip type clamp that holds in the filter. It's around the outside of the body of the filter and lifts up and away to un-clip. Take the clip bracket off and put it aside. Take some rags and put it under the hose where it comes into the filter. Now remove the hose. It's best to rotate the hose back and forth around the filters pipe to break it loose, then pull it off. Sometimes this part can be a bugger. You may need to use pliers to rotate the hose loose (be careful not to damage the hose - if it gets cuts in it you will have to replace it). When the hose comes off some petrol will dribble out, so make sure you have a rag under there.

After the hoses are off and you have the filter out, remove the plastic clip from the top and put it on the new filter. There is a rubber sleeve on the old filter too that needs to be removed and placed on the new filter too. The rubber sleeve is where the clamp holds the filter in place. Notice on the new filter there is an in and out pipe. The in is toward the outside and the out is at the center. Put the new filter in place (don't clamp it yet) and attach the two hoses, slide the clamps up and tighten them back down. Don't go crazy tight, you don't want to go so tight you cut the rubber, just make it nice and snug. Now put the clip back on and clamp the new filter in place. After that, clip the hoses back in the plastic holder clip.

Now start the car, it may take a few cranks, the fuel has to fill up the filter first. Let the car run and check for any fuel leaks. That's it.

Can someone please clarify exactly what models came with the new designed fuel filter? It is 2005 onwards Impreza, Legacy, Forrester and STI in the US market, but not sure for AUDM.

If you encounter cylinder misfire codes on Subaru vehicles equipped with the OBD-II (OBD2, OBD-2) system, check the past service history to see if the vehicle's fuel filter was recently changed.

There is a short period of time when the vehicle is first started, after the filter has been changed, when the cylinders may not get the fuel charge they should. This may translate into a slight cylinder misfire, which is enough to trigger a misfire DTC.

If the fuel filter was changed recently, clear the codes and test drive the vehicle. Chances are good that the codes will not return if the filter change was the cause of the problem.

My Subaru Liberty RX gen3 Sept/1999 has the intank fuel filter and no external filter in the engine bay. It used the same in-tank fuel filter as a 2.5L turbo forester part no. 42072AE000, along with the o ring 42025AE020 and gasket seal 42025AE030
These parts where originally bought for a turbo forester...
I hope this helps out
