After taking out the fuel tank and putting in new one with fuel pump replaced the old connection lines were rusted and got broken. Is there any way to tell were the two similar lines go to which line?

Good afternoon,

The large line or 3/8 line, is the supply line to the front. From the pump, it goes to the fuel filter and then to the motor fuel rail.

The return line goes directly from the pump to the fuel rail. It is a 5/16 line.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
