On the cork question, plain cork will work fine, but rubberized cork from an auto parts store is easier to work with in terms of cutting and shaping. If the gasket is made correctly, install it clean and dry with no sealer. I believe you can still purchase the cork floats and cork gaskets ready to use from your local dealer. Or, make your own to save some cash. I’ve made my own cork gaskets used on the double line pressure tanks for years now. It also works great under a newly installed transom board, for leak and vibration issues. Auto parts stores carry various thicknesses of cork gasket material in bulk rolls, or in sheets.
On how to clean the inside of the tank…. I like Castrol Super Clean along with HOT water. Use full strength if it’s really nasty. keep the garden hose handy to rinse the outside, cause Super Clean can damage paint if left on to long. I usually buy this stuff in the 2 1/2 gallon jug, and use it on the shop floor, gas tank cleaning, diluted for cleaning boats, etc,etc.
