How do you replace a fuel filter on a 2003 subaru outback 4cyl 2.5 litre

The filer is located on the left side of the engine compartment by the strut tower. Usually it is held on by just a snap type clip or in some cases you will have to loosen the screw that simply holds the filter tight by a clamp. You will need a phillips head screwdriver, loosen the three hose clamps on the top of filter to three fuel lines.carefully pull the hoses off the fittings and reverse the proceedure. Have a rag handy to claen up your mess if needed. Also dont over tighten the clamps when installing, they are pretty cheap. let your car run for a minute or two, shut it off and check for leaks. Hope this helps ya, please let me know.
