Any hose should do in the meantime until you get the right one from Honda. These type of parts are normally only a couple of quid.
I will ask @newkid if he can grab one of the 5th gen vtec auto - should be the similar if not the same

good news if that fixes your rev/idle issue 
newkid is going to grab the fitv hoses off the 5th gen and we will see how they compare to the ones on my BB4

Here is a pic of the hose that goes from the fitv to thermostat housing

I had to replace this hose on my BB4 about 6 months ago as had same problem as you - it had a tiny pin hole in it which only showed up under pressure
I also had to replace both the short hoses that go the oil cooler - again leaks only showed under pressure
