Can a petcock be soldered??

[Maggie]

Hi all!

This question is actually with respect to my Suzuki Marauder VZ800, but it could happen to any bike. The nipple from the petcock that attaches to the fuel line below the shut off snapped off. Fortunately it happened when the bike was being reassembled from a valve adjustment, not while on the road. A replacement part is about $112 on Ron Ayers. Do you guys think JB weld or soldering would work? Something that is obviously impervious to gasoline.

What would you do???
