Radiator hoses

I've just been checking out the photos of Member Topcat (WA)'s grouse-looking troopie's 6.5 litre donk. The thing that hit me was the use of the coiled-up (reinforced???) radiator hose at the top and probably at the bottom as well (but that is not shown).

Does anybody have any stories about these type of hoses? I've got a nasty feeling that the bottom hose of the Patrol is getting sucked in when it is under heavy load. If so, I'm considering changing it over to one of these ones that has the coiled-up wire reinforcing in it.

Any ideas would be gladly rec'd.

Thanks
