Never fear, help is here!!
Well its simple, Open the gas tank first in order to release pressure in the fuel system , now you will need 2 open ended wrenches. I think they are a size 13. They both will need to be very close to each other seeing that the fuel filter connection and the fuel line connection are in close proximity. Well, put both open end wrences on the connections,hold one still and turn the other connection, that will free the fuel filter. any questions,feel free to ask away.
