Hello again,
I can't find any information on what hose goes where, but it looks like you have a fuel return system, so usually the bigger hose would be the return, the smaller line would be pressure to the engine, plus it would have a line from the pump to it, and the third line would be for the EVAP system. I have included in the diagrams below a blown up diagram of the fuel pump and hanger as well as two troubleshooting flow charts for your vehicles fuel system. Please go through them and get back to us with what you find out.
Thanks,
Alex
