If you look up remote mount filter you'll see a thread with how I did this on my 7.3 without cutting the frame or anything. And while it's useful now that I completed it I don't know that I would ever do it again. I had to pay 40$ for an adapter to thread on to the block, which didn't work cause the threads were too long on the oil filter mount. I had to get a giant o ring that was thicker to make that stop leaking. I had to pay over 170$ for a 1 1/6 oil filter base adapter and 40$ for hoses to go to this mount. Then I had to mount it on the frame rail cause it was so freaking heavy and the hoses can't have 90* bends or they will restrict flow.
After all of this, and my bypass filter system my 7.3 holds 18 quarts of oil roughly (17.5 ish) and I ran it 8000 miles and still had blackstone tell me it was ok. Even saying I go 9000, in comparison to 11 quarts and a FL1995 price wise after 9000 miles vs buying 1 elf7405 and 18 quarts of oil.. I think I save 20$ per 3000 miles I had it figured out to be. Which with the over 250$ I spent on the system means I'd have to go about 30k miles to start making money back..
So it does work.. and can save money.. but probably isn't worth it. If you want better filtration, better than the FL1995 but don't want all of this gripe either install a bypass filter system or my preference and what I'm doing on my 6.9 is use a Fleetgaurd LF3974 filter. 25$ here
https://puredieselpower.com/ford/94...-fleetguard-lf3974-stratapore-oil-filter.html and its an advanced "stratapore" filter which at least in my first oil sample I sent to blackstone at 5000 miles was still "ok" and it's a direct fit only like half an inch bigger than a fl1995.
