I am looking to move my fuel tank and battery to my live well. Got the battery moved successfully but need a little help on locateing a fuel cell that will fit. I have a 15' 42" jon boat with live well in the center seat. The opening is 9 1/2 in. X 23. If i could get a tank through the opening i should have plenty of room as the total space inside is 14 in. X 26".
