ok, past months i ben havin gas leaking out behind the passenger side under the car, it comes from the fuel filter hose, ok first i thought maybe something hooked it and pulled it off but cant happen where i live at,someone didnt take it off , but i placed it bak on and then maybe a week lator pop off again,then went ask someone about it and he told me could be a filter buy a new one..went to buy one and he asked me what all happen and i told him ,he says might not be whole filter could but the clip goes into the hose and he showed me how to take them out and replace it so i bought a pack of some cost like $5, did that lines snaps in better ,worked a day...last night pop off again,can it be a fuel lines that is warp? and how much to fix or replace the whole lines?
