where is the fuel filter located so I can change the fuel filter?

What is your question?

it acts like its not getting gas. first time it quit when stopped at a stop sign. had to crank and pump gas pedal, finally started but didn't let off gas and got home . changed gas filter, but it did the same again. it just slowly slowed down and I pumped on gas then just pushed pedal down, finally picked up and drove 3 blocks and parked it. no leaks or noises.

What makes this problem better or worse?

i put new fuel filter on, didnt change
