SO 45.2 fuel tank leak

[rogersailor]

Our 1999 45.2 developed two leaks over the years. 1) When topped off, followed by warm days here in the Pacific NW, the tank would oilcan and apparently break the seal(s) of one or more gaskets. The fuel would pool on top of the tank, then bleed forward through limber holes and into the bilge. Tried to solve by getting new gaskets and resealing carefully, but the fuel absorbent napkins on top of the tank still turned pink, though not in excess. Modest success, at best. 2) Yesterday, with the tank at 2/3 full, we developed a persistent stream weeping forward from the tank compartment. Am now pumping the tank empty so we can hopefully lift and inspect. Any ideas on likely cause, repair or replacement options would be most appreciated.

I also have a 1999 SO 45.2. I have not had a leak in my fuel tank yet. I am not looking forward to that. I have had a leak in my stainless steel water tank. I kept running out of water too fast, and the bilge pump kept cycling all the time. I finally made the connection and discovered the leaking tank. I emptied the tank and removed it from under the forward berth. I found the leak in one of the bottom edge seams. My plan was to bring the tank to a welder, but it was too big to fit through the door. I turned it upside down to let it dry out, and I had a welder come to the boat and repair it. That was 2 or 3 years ago, and it has been fine since.

I'm sure this will be much more complicated with a fuel tank to drain the tank and dry it out enough to be able to weld it without risking a fire. Good luck!
