[T3] FI Fuel Line Routing Queries ('73)

Ok, I've got my gas tank out and my new FI fuel hose, and I'm almost
ready to replace the hoses in the front.

There are two holes in the fuel pump mounting plate (which was missing
from my square); and I'm assuming that these are for the fuel lines that
run to/from the fuel tank, though this is not how the PO did it--his
system, sending the fuel lines over the top of the axle beam, resulted
in a crimped fuel tank return line, and a mess of gooey electrical tape
everywhere.  I'm curious as to which hole is for which hose, though only
the orientation of the fuel filter seems directly related.

Also, it's not clear to me where to position the fuel dampner, other
than the fact that it goes between the fuel pump and the left (pressure)
line through the tunnel.  Is there supposed to be some sort of mounting
bracket I'm missing, or is the electrical tape spider's web stock?

Finally, can somebody explain to me the reason for the three
inlet/outlet pump, and the seemingly extraneous line from the low
pressure return line to the pump.  T3[13m I'm more (slightly)
familiar with is the late bus one, which runs all the fuel back through
the tank to function as a heat sink and to keep the pump from recycling
air bubbles--or so I've heard.

BTW, was is the approved procedure from removing the gooey black tar
stuff that is the product of bad gas that has sat in the tank for years?
