Petcock is leaking

[JimL]

I smelled gasoline in the garage yesterday and suspected that it might be the Tourer because I had taken it out the day before to give it some exercise after it had been sitting for a while.

I looked at the petcock and noticed a drip of gasoline  on the bottom of it.

I checked the hoses to make sure that they were secure and there was no leak around them.  They appeared to be fine.  As I was unscrewing the shutoff stem from the petcock the flow seemed to worsen.

The diaphragm seemed to be working fine, no fuel flow when the valve was closed.

Question, has anyone ever heard of the petcock housing itself developing a hairline crack which resulted in a leak?  I can't seem to find one, but I need someone more experienced than me to chime in with a suggestion.  Please!

yes there is a weep or drip hole in the bottom.  I would just get the cover set and rebuild it.  I have done a couple of them, just remember and or take pictures as you disassemble, as you can put some pieces and parts in the wrong places.

Thunderbolt, thanks for the reply.  So is it possible that a bad diaphragm would cause it to leak through the weep hole?  I actually have a rebuild kit I bought but never got around to installing.

Thanks Mike, I think I will go ahead and rebuilt the petcock since I have a rebuild kit I bought a couple of years ago.  I'll use the vacuum test to make sure I got it back together correctly.
