Help, I don't know what is happening but I put a new O-ring on the sensor and it still leaked. I put 2 O-rings on it and a small bit of silicone, on the flat surface that meets the head, and it still leaked. Someone had put silicone around the wires where they enter into the sensor. Do you think it could be leaking from where the wires enter the sensor? I figured if it was leaking there the sensor wouldn't be working. I would give up but I can't stand even a small leak.
