Re: Leaking fiberglass fuel tank
Cut the top off and lay up a new tank inside. Start with making a top with a removable plate that includes the fuel supply pipe. Try and keep a green flange going to bond with the rest of the tank.
Any resin should do but I think epoxy or vinylester have better resistance. Ask your supplier.
Easy job. Some notes here WEST SYSTEM | Modifying and Customizing Boats - Wood/epoxy composite tank guidelines
