Never fails, the last turn to get the petcock rounded off the threads. (IMG:style_emoticons/default/headbang.gif)
Anyone know the size of the thread on the tank? I think the threads are the same supply and return, but I need the supply side. |

I think I can retap the thread, I just can't find the correct size.

Steel threads... aluminum nut on the line. Which do you need? I would (obviously) imagine it's the line nut.
Hit the classifieds with a WTB... should be plentiful. |
