Sorry ,I wanted  to get back to this earlier,my petcock died at 15 yrs and about 16000 miles ,which is a lot longer than most.the problem is the stock petcock is like a time bomb ,you never know when it will fail but you know it will!  I think $30 bucks is cheap (raptor) for the piece of mind it provides . while you can,for a little less by a rebuild kit for the stock one,you're still faced with failure at some later date.
