Will this filter fit my 2003 cat 3126e engine in my motor home?

I would say no. It fits the c15 a bigger engine that’s in tractor trailers. Try to get number off current filter

Not a question. Same thread but too wide for Powerstroke without pan modification. (?)

Correct. This filter is not meant for a Powerstroke.

What are the best oil, pre and secondary fuel filters for a 1999 cat 3126, 7.2l in a fl-70 freightliner?

Amzoil has one of the best oil filters and oil filtration systems out there. They remove particles down to 3 microns

Yes, very. Caterpillar makes their own filters and they are very good. I highly recommend them.
