Ford 4000 fuel line routing please help

[2006gmcdmax]

My ford 4000 is a a 69 model diesel. it has a cav pump and single cav filter head how should my lines be routed?please tell me if the pictures are correct. if you look at the top of the filter head with the front of te tractor to your right there is a inlet coming from the tank then the line on the same side coming from the tank leaves and goes to the pump. well the pump has two returns one goes to the injectors other goese back to the filter. this is where I think my issue is the return line coming from the pump is going to the arrow pointing towards the front of the tractor which would be out instead of coming in is it on correctly or no?

The number two arrow comes from the tank fuel into filter number one which is directly behind two goes to pump number 4 is the return line from pump is 4 supposed to be where your fuel returns from your pump
