2003 BMW 325i Question: Car is not taking gas,,is it fuel filter ,and how do i know if it is

Car does not want to take gas, and moves slow up hill -
Answer 1
Pull the filter and blow through it, you can tell pretty quick if there's any restriction. If it hasn't been changed for a while, it's probably a good idea to change it anyway. -

Is'nt quiet a deal to get to the filter,I am told it's installed inside the fuel tank and the tank is a completely fixed and cannot be opened and entire unit must be replaced to replace filter..I find that very odd that a filter can cause so much to replace.please let me know if this is correct because it is an expensive maintenance -
Comment 2
It's not in the tank, usually at rear RH side close to fuel tank. -
