If you read again the questions I started the thread with, they were

I'll check again but if there were others here, I would know about it.

If I die, I'll post about it. ..... Hmm. If I stop posting soon, you

No one can follow your blathering anyway...I've worked on a few oil furnaces, one was my own before we got NG here in the boonies. They have all had filters next to the furnace like this: http://i1181.photobucket.com/albums/...ps2ecf6610.jpg

I've also seen dozens of basements with oil furnaces and the same filter set-up!
