What are these tubes?

I am substantially reworking my 1970 31' Sovereign. It had been pretty well stripped before I got it, including much of the supply plumbing. I will be replacing all with new Pex and Shark Bites, but when I got to my freshwater tank, this is what I found (see attachment). I have two questions: first, did this model come with a water pump or does it work solely off of pressure? Second, does anyone know what the lines are for? I am only certain of the drain at this point, which of course goes to the black water tank in back. Thanks for any info.

There was a water pump and the larger tube at the top of the picture would have been connected to the pump and a fitting at the bottom of the tank. The two smaller tubes connected near the top of the tank are vents. These should be connected with a T fitting to another tube which leads to the vent outside the trailer. The large pipe with the white elbow is the fresh water fill pipe. This connects to the fill port located on the wall outside the trailer. There is also another tube connected at the bottom of the tank and extending through the belly skin under the trailer. This is the tank drain.
