it is either two bolts or one bolt. First take off the top small one
to releive the fuel pressure, be sure to have a rag handy. If it is one bolt then it isn't that hard. But you will probably need to get 2 channel locks for it. Lock it on there really tight, have someone hold the other one and give that Bi*@h some force. It should come off. Replace all the metals washer on it that come with the new fuel filter. It should run like a champ afterwards.
