I'd be getting a metal tap - the braid & tap are available in any plumbing store (no doubt Bunnings) The braid is just S/S hose which has a rubber tube down the centre (used for shower attachments etc) - cut the ends off & pull out the rubber hose...
I bought my hose in Bunnings - but beware of what you pay for. The braided hose in the plumbing section may not necessarily be any cheaper than the pre-packaged washing machine hose "Boston" brand (US obviously) that sells the same hose in 1800mm lengths IIRC.
Don't just grab a length of "Happy Hooker" hose and think you're done or you might be getting ripped off.
You will get the SS braid from Bunnings as previous you have to chop the ends off and remove the rubber innerpipe , you wont cut rthe pipe with a hacksaw or tin snips but a common pair of scissors will cut it easily .
I have used copper pipe to make the connections until I can lay my hands on some SS fittings .
Mine was done on a bit of a rush but is surely has done the trick .
If you connect it with SS hose connectors watch out make sure you ask for all SS a lot the screw arrangement is not SS.
Take care those strands of ss are prickly buggers and dont half hurt !!
OK I have been out and about looking for all my parts, I got most of them from tradelink but I was having trouble finding the ss mesh hosing, I now see above you recommend bunnings which was one of the places I went and bought something, I just wasn't sure if I got the right thing or not.
Anyway I have a pic attached of what I bought, it was $14.80 and I think it is 750mm
