If you follow the bulkhead you can do it in Tube all the way, just have to get it lower than the fuel filter along the bulkhead so it drains nicely. The only piece of Hose should be the final connection to the filter, for maintenance, and at the tank. You will have to deal with the flexing of the engine on its mounts so the Tube should be fastened to the bulkhead and then run free the couple of feet to the filter. If you make it from one piece of Tube no leak issues. The steel line is less than $20 in bulk.
