Looks to me that the fuel hose end was modified from the original crimped-on banjo connector to a connection with a new hose clamp. That hose clamp is the wrong one because it can and probably did cut into the hose end and pierced it. Yo probably have to empty the tank by siphoning it out from the fuel level sender hole, disconnect the banjo connector from the fuel pump and inspect the fuel hose connection there carefully. Maybe you have to cut off the part under the hose clamp and reattach with a different hose clamp where the tightening screw does not cut into the hose. Those are available at a auto supply store. I forgot their names.
