I just changed mine and it can be done from inside fenderwell without removal of anything. There's enough room to use an oil filter wrench to loosen. One reccomendation though, Completely drain the filter, not just a cup full as recommended from installation instructions in new mopar filter box. I had to turn it on it's side and slide it out in front of the axle. You can install the new one through the fenderwell with a little convincing on the plastic. It's a little hard to get it started. I have fairly large arms and hands and could work them from up top to screw the new filter tight once I got it started. It primes very easy. Just bump the starter and release the key and fuel pump will continue to pump about 24 seconds, then try again. I had to do this twice and then the truck started immediately and no air in system. Hope this helps
