Hey all, just purchased a lightly used 1998 Bass Boat with a 15 Gallon inboard fuel tank. I was told by a rather honest seller that the fuel tank has not been used in 7 years. I did the old sniff test it smells like old fuel (bad) but I cannot confirm of there is standing fuel in it. I want to used this tank with my new outboard. Any suggestion on cleaning it out and prep it for use this summer? Thanks in advance!
