Would also like to suggest that a good 'range rod' is in order.
Too, go to your local auto parts store and get a small tube of either copper or aluminum based thread lube made by Permatex. Remove your nipple and apply a very,very small amount to the nipple threads making sure to not get any near the flash hole of the nipple. Makes future removal very easy.
I understand you can also get it in a tube similar to a tube of Chapstick which would probably be less messy.
As Sure Shot said, make sure and get back with us.
