1st fuel filter switch... i got some ?s

ok ive been told by a local valvoline store my fuel filter is in a great deal of bein changed. i know its better not to listen to those shops but ive read about how often they need to be changed and i verified it myself. its got a bit of rust to it. q#1. how hard is it to do this? #2. is this relativly like an oil change? #3. will gas leak in between changes? #4. what else should be replaced along with it? #5.how long would it possibly take to do? #6. whats the average price this will possibly run me if i do it myself? im askin cuz i havent read about it or have been told about how. im just askin before i rush into things and leave myself :banghead:. thanks to all who reply!

It might be helpful to state the year, model, engine size, and mileage of your Century so people can weigh-in.

i completely forgot about that. my bad. (3 am and not thinkin at the time) its a 91 with a 2.5. thanks for pointin that out to me.
