Gotcha that makes perfect sense. Who knows how much fuel is getting through that check valve. Enough to destroy the sensor. I suppose I can use the old oil in my pre-mix for the aluminum boat and motor if I mix it a bit heavier than 50/1. Well thanks a lot for all the help you two. It’s been an expensive season for this boat. I had to install a new steering cable, then a new starter and now whatever this oil tank and sensor will be. But on the bright side I’ve learned some and the boat will in much better shape.
