For Legacy and Outback models without turbochargers, between 2000 and 2003, and for Forester models without turbochargers between 2000 and 2004 that have an external fuel filter in the engine compartment. These models also have another type of filter which is a part of the fuel pump/fuel level sending unit assembly. External fuel filters located in the engine compartments are supposed to be changed at specified intervals. In tank filters on these particular vehicles do not get any scheduled maintenance however you should inspect them, clean them or replace as necessary whenever you are removing the fuel pump/fuel level sending unit. All other models lack an external fuel filter in their engine compartments, instead they rely on a filter that forms an integral part of the fuel pump/fuel level sending unit. On these models, mileage or thirty months whichever comes first is used as a standard period for maintenance. Always make sure that this work is done with a cold engine (after sitting at least three hours). Put rags or newspapers under the filter to catch any spilled gas.The petrol filter is located on the left-hand side of the engine compartment (the carburetor upon which it is fixed stands by the firewall near master cylinder brakes).To replace it undo clamps and push them down hoses beyond fittings on filter. With care twist off each hose from it; if they're worn-out, now may be best time to install new ones.Get rid of manifold by unhooking those clips holding it then plug out old one & fit back fresh before repositioning holsters plus tightening clamps firmly; just ensure pipe from tank points IN label exactly where marked above so rev up your car carefully while confirming whether there are visible leakages connected via pipes leading into different parts of this assembly such as "OUT" meaning exhaust system.
