I actually rigged a temporary fix for mine since I was 100 miles into a 1500 mile round trip when I first discovered my leak. I was able to cut a slice in the kinked part of the hose and insert a piece of plastic tubing into the hose as a splint. Secured with two fuel line hose clamps and voila, no more leak. Since I'm under warranty, I then took it back to the dealer after my trip for the warranty repair. If you really fear the dealer, at least take a look inside the pillar. If you have a leak, the water is going to damage the affected electronics, and any airbags that get wet too.
