The bolt going into my 97 blazer fuel filter seems to be rusted, and stuck snuggly in my fuel filter (i think its never been replaced, just bought the blazer). Now i went down to my local repair shop and they said to replace it i would have to buy the entire fuel line from the gas tank to the fuel filter, from the dealership. Do yall guys know any good penetrating oil or any tips yall could give me in getting this thing unstuck, or do you know where i could buy this fuel line (i know the dealerships are always overpriced). Thanks.
