I need to replace the hose that connects the deck filler to the fresh water tank. Any reason why I can’t use plain white sanitation hose?

Normal to use ordinary reinforced plastic hose.

It is expensive if you are buying some specially !
Some people would be funny about it...... like using toilet paper for blowing your nose.... bloke I once worked with would not do that!
Strictly I guess food grade hose is the "right" choice. ....... and less expensive than sanitation hose

If you are going to drink the water it should be food grade hose.
https://www.sheridanmarine.com/search/query/drinking+water+hose
Only three of the hoses we found were suitable for drinking water, or marked as ‘food grade’.
This isn’t an issue if you’re just looking to wash your boat down, but to fill a water tank it’s worth spending the extra money for a food-safe hose. Some plastics, often present in garden hosepipes, can leach bisphenol A (or BPA) used in the manufacturing process into the water, which is a potential health risk.
Manufacturers recommend running the hose through before placing it in your tank (a good idea anyway), to clear any nasties from the pipe. A food-safe hose is a wise investment!

The normal hose is the clear braided hose illustrated there - normally 38mm. The food grade hose is 12mm for the plumbing system.
I have never seen anything other than normal braided or perhaps coil reinforced plastic hose used. It does not need to be food grade because water is not stored in it.

The Seaflow plumbing hose is suitable for water transfer of liquids such as mineral water, fruit juices and other liquids up to 15% alcohol content.The hose is therefore suitable as a fresh water transfer hose on board boats, caravans and other similar applications.
The Seaflow plumbing hose is food grade which leaves no taste or odour in compliance with European Regulation 2007/19/EC. The hose is strong and flexible and is constructed from non-toxic plasticised yellow PVC. It also features a shock resistant PVC spiral to protect it from crushing, abrasions and weather. It can be used to replace Luisiana hose and this hose is also R.I.N.A approved.
This plumbing hose is 38mm inside diameter. (see 412751 for 51mm ID). Priced per metre, we cut this water transfer hose to the nearest whole metre as you require, up to the full coil size of 50mtrs (412738-50).

This is about hose pipes from the marina tap to the boat, not the hose from the filler to the tank.

I've re-read the article and I'm sure I am not mistaken:
"It’s long been the case that marinas across the Channel don’t supply hoses, but in the past few years marinas in the UK have been removing theirs at an alarming rate too. That means that if you want fresh water, either to wash down your boat or fill your water tanks, you will need to carry your own hose".
If it is recommended that "food grade" hose be used from the filling station to the boat then surely all hoses for potable water on the boat should be "food grade" too?
There are all sorts of toxic substances in our households/environment which are known to be health hazards we don't need to add such substances as BPA or lead.

This is a very contentious issue. The concern with leaving hoses attached in marinas was primarily about legionaires disease and falling in seawater that might result in it contaminating the mains supply. The former is a bit of a red herring as the conditions are not right for that disease and the latter mostly solved by non return valves in the plumbing.
There is little if any real evidence that suggests any health hazard from water on boats, never mind any contamination resulting from using marina hoses. However once an idea gets going, whether there is any evidence or not it quickly becomes "fact" and many marinas removed hoses so boat owners had to use their own. difficult to establish whether one's own hose is any "cleaner" than a marina hose given that it is usually stored away with water still coating the inside. Using marina water with or without the supplied hose is common and those who are concerned about water quality use one of the purifying systems.
Back to filler hose. Water is not stored in it and I fail to see how it represents a contamination risk given that the overall contamination risk in a boat's system is so low. I agree with using food grade hoses in the plumbing system because they are always full of water. by all mean suse the food grade if you are worried, but I think any concerns are misplaced.

Last comment I promise!
I understand what you are saying regarding the small risk of using non food grade hose.
My point is that the incidence of diseases caused by toxic chemicals and our environment are rapidly increasing in the Western World so why take unnecessary risks?
"What’s more, prevalence rates for some of these illnesses are rising for what Miller says must largely be environmental reasons. “Our gene sequences aren’t changing fast enough to account for the increases,” Miller says. “Yet our environment is—we’ve got 80,000 chemicals approved for use in commerce, but we know very little about their immune effects."
Have a good day!

Strange how Aussies, who we always used to regard as buccaneering divil me care folk have recently emerged as the world leaders in pedantic bureaucratic regulation.

There's some truth in that, Quandary. Time was when every would-be bushman in Sydney had a 4x4 sporting 'roo bars. Now it's more like rue bars.
(Except, perhaps, in the bush itself. I well remember a (very basic) bar in Birdsville, with a chalkboard promoting their "seven course lunch - $5". Underneath was the legend "six pack and a pie".)
