My boat is in our backyard this season sitting uncovered for the summer. By chance I climbed up on it last week and discovered diesel fuel in the bilge. Cleaned that mess up and brought the fuel to a shop that can burn it in their boiler. About a week later looked again and more fuel in bilge. Determined fuel coming from tank so we pumped out about 30 gallons and pulled tank. Found some areas of either chafe or rot on very bottom of tank. Considered having a shop repair but decided to go with new. Called Berry Sheet Metal and Cliff is still in business and has the original drawing. Prices have gone up with covid I guess, new 40 gallon tank with new sending unit $600 plus shipping to Maine. My boat is an 82 33RH. Like the idea of new rather than 40 year old repaired tank.
