I'm replacing the fuel fill on my 83 cuddy, center tank. The hose is pretty stiff, I accessed mine thru a deck plate in the gunnell, also pulled off the gas fill, You mah want to pull the gas tank hatch for more clearence. I pull it loose from the fill first, then the tank, I tape a piece of heavy cord to the hose before you pull it out so you can attach it to the new hose and pull it back through. You should be able to get the fuel hose - use the marine fuel hose - at any boat supply place
