    Removing fuel tank from a ceirra 2855 year 2000 after leak

    Hi has anyone got any advice on the best way to remove and repair a leaking fuel tank? We’ve checked slm the engine seals so it’s come down to it being a fuel tank issue. Many thanks

      There's no repairing it. Must be removed/replaced through the aft cabin. Motor also needs to come out. Major job. Currently there is thread on BOC Facebook page. Lots of details there. Perhaps you are the same person.

        Cant really repair it effectively or safely. Coastline marine in Bellingham Wa. probably made the original or can make you a new one if you cant get one from the factory.

        leaking fuel tank is nothing to play with. There is also a good chance that the bunk holding the tank could be rotten too. The reason being the tank rotted because water gets under it and can't get out.

        third part of that repair should be working on a method to keep water from getting under or on top of the tank. In my case it was the side engine vent that dumped wate directly onto the gas tank.

          If the fuel tank is in fact leaking it'll need to be replaced along with all fuel related hoses while your there. As msd said, it's a major project.

            $3000.00 CDN all in replaced by a pro. Engine out, it was already out being replaced that is why I changed the tank before it leaked!!. firewall was removed mid birth floor removed stringers cut didn't want to mess with a 18 year old tank. Determined once removed that I had about a year left. Did not want 100 gallons of gas in the engine bay. Wanted to stay out of the evening news

              That’s a great price.
              My 105 gallon tank alone was $1000 US purchased directly from Coastline 4 years ago, the cost today would likely be more.

            The bunk that the tank sits on was completely waterlogged in my 2859. Was no small job thats for sure. The limber drains were all 90% blocked with fibreglass from the factory chopper gun. The main drain on the bottom was angled upward under the tank so water could run in but never get out again. Once you open that can of worms ........be prepared for alot of extra unseen work that these older boats all have. A survey will never be able to tell you about the stuff that cant be seen or reached. And thats the stuff that will cost you the most to fix or replace.

                I agree with all of this . I had a leak in my tank on my 2859 and had the boat yard here in SOCAL do the work. The cost of the tank alone was about $1000, but the labor to remove and replace the engine and cutting out the floor in the mid birth ran the bill to about $4000( high CA labor rates). This is a major repair. Good luck!

                  Many speak of the high cost of the repair. Here is the deal the tank will be about $1000.
                  mine were $800 plus shipping.


                  However beyond that the actual material cost will probably fairly low. Maybe a few hundred or so. The real expense is labor cost. It adds up fast.at $100 per hour.

                  if you know how or want and can learn to do it yourself a major money savings can be had.

                  on top of that a estimate is usually somewhat padded for just I cases. For example I replaced my tank and bunk in a weekend. I didn't have to pull a motor though.

                    I too have a 2000 2855 (newer hull style) My tank appears to be plastic and its original. It's not leaking.

                      Bought my tank at coastal with dealer markup it was just under $1,100.00 cdn remember my engine was out anyway so not counting engine removal. BTW engine replacement from 7.4 to stroker was a 3 man day project including sea trial

                        If you have a roto molded plastic fuel tank they tend to leak from the fuel sender flange which is on the top of the tank. It's an easy fix. Just something to check before you rip everything apart..
