How do you replace the fuel filter located on a 1997 Nissan Maxima?

Answer 1

it's quite easy. It's mounted on the firewall, closer to the driver side. The filter snaps into its holder. Pull it free, then disconnect the upper and lower hose clamps. This is the tough part - getting both hands in there to stabilize the filter while trying to remove the clamps, especailly the lower one. Make sure the fuel lines are clamped so fuel doesn't leak. Once loose, slide fuel lines off, and replace filter. Make sure filter is put on the right way - there should be a flow indicator arrow on it. Retighten hose clamps (I always liner them up so they are easier to remove the next time), snap filter into place, remove clamps from fuel lines, and your all set. ADDENDUM TO THE ABOVE ANSWER: Make sure you depressurize the fuel system before loosening the hose clamps. (Otherwise fuel will spray everywhere - Not Good) Do this by removing the fuel pump fuse while the engine is running. Wait until the engine stops running, then turn off the ignition key. It is easier to get at the fuel filter if you remove filter box and the hose between it and the throttle body. Only a few bolts and clamps hold it in place.
