My 97 190SX does not have the hydro-air pump installed and would like to have the ability to recirculate water within the live well. I cannot seem to find how it was installed from the factory, if anyone has any decent pics of the pump(s) and plumbing that would be awesome.
Here is what I currently have (sorry boat is torn apart but everything is in its approximate location). I do have the hydro-air timer and is wired just never installed (was told it was a option and installed after the fact).

Here is a pic of inside the live well that shows the aerator and overflow.

So my thinking is to tee into the livewell drain with a and install a pump that will draw water from the bottom of the well. I'll then tee into the line from the fill pump to the aerators and plumb the outlet of the new pump to that and in theory should recirculate water between the drain and the aerators.
I would have to install a inline check valve between the fill pump and the tee to the new pump to prevent the new pump as shown below. Doing it this way would not require any cutting of the livewell just some hoses that are being replaced anyway.

Hopefully that makes a bit of sense, I have the room in the bilge area for the plumbing. So is there a better way or easier way to do this, also any issues with using my existing aerators for this?
Next would be what pump should I use and ideas on a check valve?
Thank for the help!
