If none of the above suggestions work, can you get a bicycle chain that has enough clearance to go around the top of the filter and between it and the fuel pump? If so, then bring the ends down to where you can get hold of them and put a small bar through the ends and pull the way it will tighten the chain and be turning the filter to loosen it. We had one that we finally had to take the can part off of and use another method to get broken loose. Some people think that when they put them on, they have to be as tight as they can get them. I just put mine on hand tight and then maybe a quarter of an inch turn with the wrench and have never had a problem.
