I've checked the iboat store, my local Johnson dealer and poked around the internet looking for a OMC tank fitting. It's a standard ( I guess ) fitting that the fuel hose clips on to. It's a fitting that the hose locks onto..identical to the end that connects to the outboard. The same fitting is on each end of the hose. I really hate to have to buy a tank because the factory tank fits perfectly into the catch tray that is mounted to the boat floor ( under deck ). It also has a gauge built onto it. This seems weird a dealer doesn't have this piece.....
