Typically a infinity jet would be placed at the same location as a regular jet at the flare but it has been found that you can get much better vacuum/suction if you use a 4' to 5' section of hose between it and the flare.
So, what is all this discussion about the Infinite jet? What does it look like and how does it work? The design of the venturi generator is completely different from any other device. The actual jet is located at 360 degrees around the outside of the incoming water from the suction hose. The concept is to grab the outer perimeter of the water from the suction hose, and break the surface tension on the wall of the tube and accelerate the body of water and material. The losses in this type of jet are very minimal. Because the jet gap is so small, the jets are usually made adjustable for maximum efficiency. This has a built in advantage, if the gap was to get clogged, then it could be opened to self-clean.
Setting the gap opening is a little tricky. I used an old mining method to measure the GPM output of the venturi generator. I have discussed this method in another article, for it is too lengthy to discuss here. The basic principle is to adjust the gap for a maximum amount of water flowing out the end of the venturi generator. The suction nozzle is the other strange device. I know it works better then the straight jet venturibut I really never gave it much thought. The one big thing that is obvious, is that the output flow of the jet is inline with the dredge hose, instead of being tangent to the flow of water, you know, coming in at an angle. The jet is pushing at the center of the column of water and no losses of energy are wasted on the side of the tube. The dredge hose now provides a long column of water and material to push on, this is an ideal situation for the jet. The water and material are now coming in to the jet at an angle and get blasted into the flow. I am amazed at the efficiency of this device; it is so simple in construction. After building an infinity jet, I now understand why the simpler jets are produced. I personally like the efficiency of the suction nozzle, the tri-jet and the infinity jet, but like anything that is more complicated to build, it is going to cost more."
Here's diagram that someone made of a infinity jet or also called a coupled jet that he was going to build.
The way one works it that the tube slides in and out to adjust how much flow goes by the tapered cone.
These types of jets have also been build with a male and female cone, where the male cone is hollow for the flow through and is threaded and adjusted by screwing it in or out to control the flow

I'd like to get my hands on one of those. (infinity jet)

I also found this at the following website.

where did you get your infinity jet? I've been thinking about trying to make one this winter. I can't find any spec's online as of yet.
