    2556 Owners - Transom Fuel Tank Vent replacement

    Anyone have any thoughts on how to replace the transom fuel tank vent that is mounted port aft corner of transom?
    Manufacture used the Chrome plated zinc alloy. Thru the years of saltwater abuse the hose end corroded and broke off.
    I'm assuming these were installed before the deck assembly was mated to the hull.

    There is no way to reach the inside to mount another. Only way I can see to do it is pull the motor (not an option) or cut an access hole and install a cover plate near the location.

    I'd think you'd be able to gain access to that fitting without to much trouble. Might have to remove batteries and such off the port side box to give yourself enough room to get in and do the work. The 2556 has one of the roomiest engine bays I've seen, ask me how I know.

        Yep, the OEM Perko fittings are not the best, like you say they can corrode fairly quickly. I went with stainless myself.

      my boat has an 8" round access port in the rear wall of the cockpit which allows me to access in to the vent and filler hose clamps.... I thought this access port was OEM, as it is about the only reasonable way I can see to get to that area.

        Mine has a 6" round access located directly over the fill fitting/hose clamps, however my vent fitting is a couple feet to port of the fuel fill and a bit lower.

      Thanks, I don't intend to replace with the same material. 28 years on this one isn't too bad.

        Even with the batteries remove and being 6'3", I would still have to deal with a trim pump and hot water heater.

          I have an access port to the main fill hose but can't reach the vent from it. I had to install 2 access ports to be able to replace the 2 aft cleats. The cleats were made out of the same Zinc plated alloy as the fitting.
          Still can't reach the vent from there either.
          Guess my solution will be to install another access port and maybe use a rectangular box for storage.
