when you turn the key on before starting can you hear the fuel pump run? Should be able to hear a slight whirring sound from behind for a few seconds if not check your wires and new connections. If you can hear the pump run then it should be just a matter of "priming the line" . keep cycling the key on and off several times to pump the fuel through the line. It takes lots of cycles to fill the line and the new filter. I just replaced some fuel line and it took several "cranks" to get it running.
You can do it.
