WHere would the fuel filter be located on a 2002 Nissan Altima with the 2.5 liter engine??? My coworker has this type of car and he thinks his may be clogged. I did a quick search on google and haven't had any luck....
Follow the fuel hose from the injector rail back and if the filter is not on the firewall, then it's probably inside the fuel tank. Most FWD Nissans I've seen have it mounted below the brake booster.
