H2RICK is right, the filter removal tool is a wonderful thing.
However, when I did my B1250 oil change, I found I could not get a 3/8" ratchet OR exrension on it, the cross-pipe blocks the way.
But the filter tool also has a stamped nut-shape around the square 3/8" hole that a 17mm wrench fits on. So...
Get the engine hot and start your oil draining underneath.
On the left side, pull the hose back, reach in and place the filter tool over the end of the filter.
Now go over to the right side, reach in with a 17mm box or open-end wrench and loosen the filter until you can spin it easily.
Now go back to the left side, pull the hose back again, and reach in, remove the filter, and lay it down on the pipes hole-up to prevent spilling.
Now just leave it there until the engine cools down. Then you can reach in and remove the old filter, and install the new one.
You can always wear an old pair of gloves to avoid burns...
