Would Like Accurate Diagrams For My 30 Horse Johnson

It is a 1998 BJ30BAECS Serial No. G 04519320. Last Autumn I did a head gasket job on it due to only 90 lbs. compression in each of the 2 cylinders even with oil squirted into them. Cylinders and pistons were not scored. I didn't make as many notes as I should have because I had bought a big, thick Seloc repair manual and thought I was reasoning (but was only assuming) that this book would show me pictures and diagrams of all hose and wire routings. It did not. I found a cylinder and crankcase parts ordering exploded view diagrams for my model motor, the BJ30BAECS, but my motor isn't exactly like the diagrams, even though I didn't modify anything in the motor. For example, the primer pump in the diagram shows a tee in the outlet tubing of the pump, my actual motor has no tee. And there is a hose barb fitting behind the fuel pump (not primer pump) and another one at the starboard side of the bottom of the intake manifold on my actual motor, but no such hose barb fittings in the diagram. I don't remember for sure from last Autumn if a proper length rubber hose I took off the powerhead last Autumn in fact goes between these two hose barb fittings, and the diagram does not show a hose going from behind the fuel pump to the lower part of the intake manifold. Might anyone know if I have hooked this up right and why it isn't on my diagram, and where I would have to go to get the proper diagram for my model and serial number motor? I am attaching pictures of my primer pump hose routing that isn't like the routing in the diagram, and of the hose that goes from behind the fuel pump to the lower part of the intake manifold.

The hose between the intake manifold and bypass cover is correct. It routes excess crankcase drainage to the upper cylinder for burning.
