Water Pump Piping

[Navigator]

My new to me 73 International came sans fresh water holding tank, nor a water pump. After I install a new tank, and pipe the outlet to the pump intake, where do I connect the pump outlet to?
My guess is to an accumulator, then the hot water tank inlet.
Am I missing something here?

The pump outlet line goes to the accumulator and from there goes towards the rear of the trailer. Once this cold water line goes by the water heater, it splits off to feed into the water heater inlet line. Once a line comes out of the water heater, you now have a cold and hot water feed which go to the galley sink, shower/bath, bathroom sink and just a cold feed to the toilet. Be sure to put in a T at the lowest point in each of the lines to drain for winterizing.

Thanks flyfshr,
Thats what I thought, but was wondering if I could try and avoid going all the way to the rear, but I guess not.
Thanks,
