Is this the newer version 2?

we sell is version1 DP-4the version 2 is DP-4S, can extend another 4 pump heads

How strong is the pump? my BRS doser can't pull worth a damn.

It's not made to pull or push very far. Pumps are not strong

what is the inside diameter of the tubing? Standard airline tubing is too big. I am using the soft tubing from my CO2 diffuser.

I'm using standard 1/4" airline tubing. The nipple on the doser has a two-stepped fitting. 1/4" down to 3/16".

Would it be safe to have pump and liquid storage container on a shelf above the tank/sump? Does it have anything that would break a siphon?

The pumps are simple peristaltic pumps (https://en.wikipedia.org/wiki/Peristaltic_pump), so they are essentially just simple tubes. If the seals from the rollers inside the pump were to not seal, the pump can end up siphoning in the wrong direction. It is probably a good idea to simply leave an air gap between the output and the tank.
