hahaha that brings back install day memories...
The T1R kit came with a washer bottle, but it was nearly (ok, exactly as near as makes any difference) the same as the stock one. My buddy used a torch to heat up the plastic and dent in the top of it to make more clearance. That didn't work well.
So the way I've got it now , it's bungee corded (yes, bungee corded) to the frame at an odd angle, and the filler neck is extended with an old piece of garden hose and some duct tape.
I can't believe it sometimes, but it works!
