3600 CAV Pump Fitting

A friend has a 3600 ag tractor that has a broken plastic fuel line. This line goes from the fuel filter housing to a fitting on the cover plate for, I think its called, the timing port. The cover plate that I am talking about has a lead sealed safety wire on it. I was wondering what this fuel line does, as there is another line, a metal line, from the filter to the back end of the pump. I assume that the metal line is the supply line. There is also a smaller line coming from the top cover of the pump that I think is the return line.

Also the fitting in the cover plate was loose and pressed, not threaded into the cover plate. The plastic line pushed onto a barbed banjo fitting, with no clamp. Will try to post pictures.
Thanks

Thanks Dieseltech. What seals that fitting into the cover plate? This one looks like it is metal with barbs into a metal flange on the cover plate. Is there supposed to be a plastic bushing in there?

There were two side two bolt cover plates used, first were aluminum and latest are steel as the first were bad at leaking at the pressed together joint. Both used a banjo
bolt fitting through the return line barb with two copper washers to seal the banjo/bolt.
