If your warranty is still good, let the dealer fix it, Will.
Save yourself that anguish.

If they f something up, it's still on them.
Try another dealer than the one you've been at odds with.

Don't try patching the hose; it won't hold unless you can cut and reattach down stream of the leak.

Does your insurance cover towing?
There is a retired couple around here that own a MC towing company call EMR bike transport or some similar. Their rates are fair, great bike owning people who know how to transport bikes and care about customer service.

Before this economy, the dealer would likely pick it up and deliver back to you.
