ive had the ic for almost 2 years now, that checking on it crap is long over. i used to be all over it, cause it was actually not working all the time, not till i cut the pumps plug off and soldered the wires right to the pump.
and mines under my horn, cant hear it really, and the upper return tube is under coolant, so i dont hear or see that either.
i just happened to be flashing a tune with the hood open, didnt see any movement in the res tank, first thing i saw was the wire hanging near the battery. bingo!!!!
