I used the 40 litre aquaflow which after a leak is now underneath and seems to be OK in moderate frosts
The external Carver pump pipe to the taps was removed and used to fill the tank .This can also be filled with a hose through the same fitting.
The outlet from the tank was then connected to the inlet side of a Sureflow inboard pump and the original feed to the taps was connected to the Sureflow outlet
The original pump 12V feed via a relay was used for the Sureflow and a new feed via a fuse was fitted for the external filler pump(the original) with switches inside and outside the caravan for filling
A float switch in the tank illuminates a warning light when there is about 2 gallons left so water can be pumped in from the aquaroll when needed(from outside or inside switch)We run out water through the drain tap until the light illuminates for towing.
We have had this system for 15 years now and find it very convenient with water always available for two showers and en route and the tank can easily be topped up at inconvenient times (i e when in the middle of a shower or if its raining etc)
C A K tanks of Kenilworth would make up a kit for you
