I am having trouble removing the fuel filter on my 89 Allante, someone has tried in the pastand used vice grips so I am unable to use my fuel line wrench. I have been trying to use penertrating oil, I have used my air hammer trying to shock any rust loose. short of cutting the can I am not sure as to what to try next. I am concernedwith the line from the tank to filter as their is no room for mistakes. does any fellow Allante owners have any idea as to try next.
