I need to change the fuel filter on my car as its never been changed. Now i am having misfiring problems, ive been told to change it. Now problem is that i tried and i snapped a bolt on the filter cage, now theres only one bolt left thats holding it. I have sprayed some plus gas on it but if that dont work i have some acid at work that i can dab on the nut. Say if it breaks is it easy to get to drill a hole and use a bolt and nut from the passangers foot well or is it further under the seat base?
