i had bought the kit used from a member here, he said he would sometimes see a few degrees of kr and was not sure of the pumps condition. so being paranoid id check my res tank for flow, pumps pretty quiet, cant hear it, and some times it was working some times not, if i fiddled with the plug on the pump it would kick to life.
after doing some scanning for tuning i saw it hit 4º and its never done that, pulled over and dont ya know the pump was off. next day the plug was cut off lol
you can add a flow detector too. i was int he middle of doing that, got it all wired up, and the detector took a crap on me. waiting to find another good one that others have used already with luck.
