95 Trophy, 140 gallon tank, sensor is in back of boat. Have never worked with it, maybe should clean it up a bit... Awkward to get at though. I know people say never trust them. I am just so cheap this time of year, don't want to put much more gas in it. I run my kicker most of the time off of a separate tank as I know exactly how much gas is in it. My main is a Mariner 250 2 stroke. Eats gas when I just think about starting it....lol. Another question, when filling tank, every once in awhile I get a back flow coming back out of tank especially if I try to feed too quickly, what causes this? Thanks again..
