I would like to replace my propane solenoid and gauge.  I may want to replace the regulator as well.
My solenoid looks like this:

Mine is pretty rusty so I am wondering if there is a stainless steel version.  I also am interested in finding the part number for the gauge.  Please let me know if anyone has a good parts source for these. 

Thanks,
