Has anyone had success at adding an additional (second) inline fuel filter, prior to the injection system and factory canister filter? If so, what brand/kind? I'd like to add one that was clear, or had a view port, but had doubts about the pressures involved. I have a standard 3B and anything after the sedimenter and in the engine bay would be fantastic.

Why do you need to add an inline filter?
You have a water fuel separator, and a spin on filter.

A non-common rail engine has no need of additional filtration over and above the factory filter setup (and it's debatable as to commonbrail engines requiring it IMHO)
Is there a particular issue you're trying to solve?

I added one of the below prior to the lift pump on a 2H (same setup as 3B) - it happily sucks fuel through it. I've got 100,000+klms on it now.
I did this because I deleted the factory sedimenter and because I often fill up at very remote fuel stops who have above ground tanks and questionable quality diesel.
The visual sight bowl, replacement sedimenter/water trap, and extra protection it delivers is important to me. My factory spin on filter just before the Injection Pump is 10Micron and I run 30micron in this pre-filter. I carry two spare spin on filters and a spare filter for the unit shown below. I can bypass the pre-filter fairly easily if I need to. It does make bleeding from dry more difficult but thats never happened on a trip yet. When I did it at home I used a bit of low pressure compressed air into the tank to assist.
If you went a similar route I'd definitely delete the factory sedimenter in the process - they do rust out and the 10mm drain bolt provided rarely actually removes accumulate sediment in my experience.
