Inside a 78z gas tank

[jbc3]

I am sending my gas tank to get reconditioned and after rinsing it out and dumping a ton of rust chunks, I snapped a couple of pictures of what I could see inside the tank. I used a remote flash to take the pictures. There is a canister (surge tank I assume) in the middle of the tank. There are 4 hose connections on the tank, 2 on top and 2 in the lower side on the front passenger side of the tank.

Can someone describe the proper flow of fuel to make this tank work properly. I searched and was unable to come up with the flow. Also when I bought my car, the fuel lines were not connected.

Passenger side lower connection are fuel out and fuel return. larger hose is fuel out to pump. Connections at top are for vapor return. Good luck with tank- Looks pretty bad.

Thanks for the replies, they will help. The tank looks rough on the inside, but still feels solid and is in excellent shape on the outside, so it is a good candidate for a recondition. They will replace the internal tank and lines if they are trash. I was also looking for the flow in the tank itself and the way the internal surge tank is used. How is it filled etc... I have a large external pump I am planning on using and I want to make sure I understand how it all works.
