it's usually pretty difficult. The fuel pump is located inside the fuel tank, so you have to drop the tank out of the vehicle to change it.
On top of the fuel tank most probably need mechanic to replace for you.

the fuel filter is not in the gas tank. on most cars, it is on either side..search to see how yours look. you cant clean them yourself. buy a new one for no more than $16 and you can change it yourself. all you need is a 5/8 ranch and a pair of plyers
See a mechanic! I can guarantee you can't do it by yourself you need pop the hood to get light under the avalanche and then unscrew the bolt closest to the light then push.
How often need to change the fuel filter for a 2001 BMW 325i?"
