How do you change fuel filter 1998 Nissan altima?

It was really easy actually. It is located on the back, left side of the engine. It is a small metal cylinder connected by two, clamped tubes. It is pretty much a chop and swap. I suggest removing the fuse for the fuel pump and then start the engine in order to depressurize the line. Even though I did this, there still will be some gas that will escape from the filter and the line so be very careful! But it is very easy to do though.
