Additional safety !!!!!

[DuMaurier 7]

Recently I ran into a problem that cost me two apex seals and some other engine parts , now I haven't gotten the DDS2 yet so I had no "low Flow" protection . What happened is this , the suction filter for my pump became clogged causing the pump to loose suction , I do have a run light and was able to pick up the problem after I saw that the pump was staying activated a long time after I stopped boosting (it only runs a few seconds at a time) , during the "run" I was thinking that I had used up my systems reserve (three accumulators) and the pump was directly supplying the water for injection.
When I stopped and popped the hood the water pressure gauge was reading only 30psi .!!!
I have since installed a little system to monitor the water pressure , yes I know that I could use a gauge but , I dont have room for another (I have 10 additional gauges in my 7) and during a high boost , high speed run , gauges are the last things I look at !!.
What I put in is a pressure switch that triggers a relay when the pressure falls to a preset low .This illuminates a warning light and simultaneously kills power to my boost controller to allow the wastegates to immediately reduce the boost to 3.5 psi .
When I get the DDS2 I will have both pressure and flow protection , hopefully saving me from another disaster . :?
