Hey guys I have a 1984 bayliner trophy 2060 that I recently purchased. This weekend I filled her up after months of redoing engine only to get my bilge full of fuel. No I did not pump into see I safely removed and took to hazardous recycling center. So overnight I lost almost a half a tank so I doubt it’s a leaky hose. I’m going to pressure test tank to see if tank is the failure. So my boat has an aluminum 40 gallon tank and it’s currently non accessible and will need to be cut out. No foam but the tank is in the decking. So what tools would be preferred to use for the actual cuts and also when I’m done resealing tank what would be best repair for floor on a budget? Needs to be strong as high traffic area on the stern of boat. Saw a product from west marine called marine Tex say it’s dries like steel. Trying easiest cheapest fix. Area is about 14”x 65” thanks in advance guys
