How to change fuel filter in 2001 Blazer

Question

We just replaced the fuel pump and now the car loses power when driving and you have to floor the gas for it to go. Went and had the codes ran and it says too much air in the fuel!

Suggestion was to change the fuel filter and we found it but how in the world do we get the old one out? Looks like a lot of stuff in the way.

Also, would a defective fuel pump cause this problem as well as when you turn the car on there is a loud humming sound by the fuel tank. Never heard that before either.

HELP!!!

Thanks,

Good luck!
