Mine got smashed when I slide off a trail into a tree. I fixed it by putting a screw covered in some JB Weld into the end of the house. Works just fine and cost me a screw. Now the line is short and the screw is on the wheel well by the battery.

 

I just moved it inside the engine bay and tie-wrapped it over the oil filter. It's been over 6 months and everything is fine. I'll try to take a picture of it tomorrow.
