Considering Holley sniper EFI for my 1969 340. Thoughts from people who have that set up?

I think the Camaro setup is at least equal to the surge tank.

The article I linked above said:

Over 800 on-track and 3000+ street miles were put on the fuel module during testing.
At no time did the engine suffer due to fuel starvation except when it drained the tank dry on a road racing course.

Don't forget this is the OEM's solution for probably all late model cars.

In addition, the following components are no longer needed:

1. External filters
2. External pressure regulators
3. Return lines
4. Fittings, mounts, clamps, etc. to connect it all
5. The room all of the above components take

No idea what the surge tank setup costs, but I see the Tanks Inc kit on Summit for $530. The Camaro setup I built could use a $130 Spectra tank or a $180 Tanks Inc non-EFI tank and a GM fuel module for an LS3 is $155 on RockAuto plus a $15 adapter and a FPR to replace the release valve. I spent $100 to buy a late model GTO tank I cut up for the ring. So $430-480 plus some tax and shipping for the Camaro setup?

Frankly, the Camaro setup requires fabrication so the Tanks Inc kit is the easy button and isn't that much more expensive. And if people aren't having issues with how the tank works with low fuel, seems like a reasonable solution. I am curious how the Tanks Inc setup work in a hard use autocross and/or road course, but for most people I am sure it is way more than enough.

I have heard reports on the Holley sending unit replacement working really well, too. It's currently only $373 on Holley's website and doesn't require a new fuel tank or return lines or FPR. For the OP, that's what I would recommend. Wouldn't even have to swap out his hard line, just plumb the Holley pump to it and wire it up and call the fuel system done.

Depending on how much power you are trying to build, a surge tank (less pump) begins at around $65 bucks and up. Competition in the Surge Tank Market has driven down costs since I did my install 10 years ago. At that time, the GM high performance EFI fuel module stuff was in it's infancy compared to what's available today.

Then figure it takes 2 fuel pumps, one in the stock tank attached to the factory style pick-up and one in the surge tank starting at $65 each. Also the cost of a pressure regulator plumbed on the high pressure circuit between the surge tank and the fuel rails.

You would need to increase the size of the fuel return line to match the outlet size and plumb everything, I silver soldered mine and run 2 Permacool 10 micron water trap/fuel filters in-line on the low pressure tank to surge tank circuit. I ran 7/16ths aluminum fuel line and rubber EFI hose to keep cost down.
