I noticed coolant coming from the weep tube on the water pump after a short ride yesterday.  I've searched the forums but have not found much on second gen water pumps.   
1. Is there a new/rebuilt water pump available.   
2.  If not one, what parts should I order to complete the job. 
3.  Are there any special tools required or gotcha's I shold be aware of in taking on this task.   
I recently had to change my radio controller and found the best price for a new one at Babbits online.  I am open to suggestions, recommendations and any other help anyone can provide.
