Wow, what an ordeal. I'm glad you made it home safely.
It might be worthwhile to keep several lengths of the various size rubber hoses that fit your bus on hand as spares, along with good hose clamps. Sounds like having that option might've saved you some money and time. After reading this, I believe that's what I'll be doing.
Hopefully the fluid sprayed around your engine compartment won't cause any other issues for you.
Wish I could've seen that groups of crowns together. Sounds like it was a blast. I think the crowns and gilligs are by far the coolest school busses ever.
