Diesel system layout

Hey guys. After having my diesel lump rebuilt on the 2a im now ready to start plumbing the fuel system back together. Trouble is iv forgotten what goes where and the diagram in my haynes doesn't match how it was setup before

For a start I have 3 ports on the fuel pump. I specifically remember the fuel filter had 3 points of being connected where as this says 4. I need some advice please

you have a feed from tank to lift pump, then from lp to filter then from filter to injection pump(filter head has arrows to show flow direction)other pipe on pump returns to tank, leak off pipe from no4 injector goes to top of filter head

You sir......are my hero

On a side note. Does anybody have a picture of the diesel distributor specifically around the throttle linkages and the engine cut out? After having it back from the rebuild I'm not convinced they're in the right place. Sadly the haynes doesn't have a diagram at all for this
