I have the same setup as Bill. I did go back and forth with installing a 90 degree B&C adapter with the Plane Power FS1-14. Ultimately it ended up being too much of a pain, and the oil filter in its standard configuration is not in that bad of a location for me to deal with that pain and extra gasket in the path.
I do have a 90 adapter and spacer if you are looking for one. I was too lazy to return it and I have not got around to putting it in the classifieds.
