That white covered food grade hose is not at all suitable for direct connecting to the inlet of a poly caravan tank. I was under the impression you wanted to use the thread tape because one of the threads was leaking.
On the fill hose use a piece of soft clear good grade hose, which should be such a snug fit the hose clamp only needs to be done up a little.
The white covered food grade hose can then be connected with a cheap poly line connector you buy at an irrigation shop
to the clear poly hose. Leave about 150mm of the clear hose before connecting the white hose. The only way you can use that white covered food grade hose is if there is no movement of the tank or hose at any time. You used to be able to buy the soft food grade hose in black, but it is no longer available, so what you will need to do is put black insulation tape over the clear hose to keep the light out as that is what causes contamination of the water.
You can get a cheap breather tap from the garden irrigation shops for $2.50 or thereabouts.
