I came by a 17 gallon permanent fuel tank at a swap meet for a price too good to pass up in a size that will just barely fit my boat. The problem I found when sizing it up against the spaces in my boat that would accommodate it is the fill neck and vent are molded into the top of the tank, and there won't be enough space above the tank to complete the fuel neck.
I'm inclined to just cut the neck off, plug the area with a plate & gasket and drill a hole elsewhere and install a flush flange with a venting screw cap (something like this https://www.ebay.com/itm/JAZ-6-Bolt-Flange-Fuel-Cell-Filler-Plate-Kit-P-N-350-201-06/292652644372?epid=663430398&hash=item442374f814%3Ag%3AwzEAAOSwD9pbVkJ9&_nkw=fuel+tank+flange&rt=nc), but before I do all this I wasn't sure if there's anything I should be concerned about that I'm not thinking of.
When finished the plan would be for it to be in a vented compartment below the rear deck permanently attached to the hull with the std. gas tank retainers. I would open a hatch cover to gain access to the fill cap.
