Correct in the routing but I'm not so sure about the hoses being "good".

I'm not sure if the return line was always below the surface but I didn't notice any bubbles.

I did not see any bubbles in the line exiting the lift pump, it appears to be filled with fuel at all times.

If you fill the secondary cannister filter before starting to attempt to bleed the fuel system you will make everything easier of course.

The filter was filled and I removed it to verify that it was still topped off, it was.
So how is it that the canister is full, the line going from the lift pump to the canister is full but the line coming back out of the canister and going to the IP keeps drying up?

I don't understand how or why but perhaps the electric fuel pump pressure is interfereing with the lift pump operation somehow, to eliminate that possibility just use a section of hose and no electric pump from your fuel container.

No electric fuel pump moving fuel out of the container, just pulled the lines that would normally go to the tank and dropped them into a glass jar filled with fuel.
