Are you concerned about the weight of the return line?
I bought the C5 combination regulator/filter to mount on the frame rail next to my LS swap. There are several threads on here that do it. I'll add a link if I find one...
Is the damn internal fuel pressure regulator! I’m going to an external regulator. Anyone do this?
Yes, many have done the external regulator. In fact, the internal regulator in the Sniper 1 is considered junk by most. One of the first things I recommend to Sniper users (besides ensuring they run the main power leads directly to the battery) is to NOT use the internal regulator. I have completely removed the internal regulator and put a block off plate there and added a pulse dampener instead. I went straight to the external regulator due to my boosted application, but I'm glad I "accidentally" moved on from the internal regulator. In fact, the Holley abandoned the internal regulator for Sniper 2. That shows how reliable / effective the internal was.
A picture is worth a thousand words...
You can see the Aeromotive regulator (boost referenced) to the right. Then there is a Radium pulse dampener on each side of the fuel rail. Having two is overkill, but I had two because of a different project that ended up going in another direction. So I installed both of them.

I hope this helps!

What is the pulse dampener for? Do I need one? Where do i get that?
What it's for is to dampen the fuel pressure spikes and drops as injectors open and close. Some OEM applications use them as well. I run one in each of my fuel rails
What is the pulse dampener for? Do I need one? Where do i get that?
As described above, they are devices that dampen the pressure pulses created by injectors opening and closing. Do you need one? Not necessarily, but they do "smooth out" small rapid pressure changes. Many modern EFI systems have a form of pulsation control. If you haven't had any problems with your Sniper including tuneability issues with fuel delivery, I wouldn't necessarily run out and buy one. Radium has them and they are well made, but not cheap. However, adding them to your system won't hurt anything, and will smooth out your fuel pressure to some extent. You aren't going to "feel" a difference, but you can "see" a difference if you have fuel pressure monitoring built into or added to your Sniper. Repeatable tuneability becomes a little more accurate with pulse dampeners, but most user's wouldn't necessarily notice that. I hope that helps...
