Funny you should bring this up as I purchased 2 of those hoses (17545-MCS-G00) around 5 or 6 weeks ago.
I purchased them from Warragul Powersports (
https://warragulpowersports.com.au/) here in Victoria for what I consider a bargain price of just $16.84 each.
They never had them in stock but they got them in within 2 days and even though I was going to drive over to pick them up, they actually posted them to me at no cost so I'm more than happy to recommend them.
