Trying to interpret what the problem is.
What are you trying that isn't working? Access? Tight screws? ??
Piedmont,are you talking about the spin on filter, or the sediment filter?
I had the same problem with my spin on when I did my 50 hour. I just used a very large set of channel lock pliers. That,or a strap wrench may work.

The spin on filter. I have had the channel locks on it but was afrasid to lean on it to hard because I was afriad I was going to bend something.
Had the same issue on my 2305, used a strap wrench and came off without damage. Follow RoyJackson's advice.
