Have gas hissing out of the spot under the yellow mark on the left side of my regulator. Any idea how to fix that or what is going on? I can’t figure it out.
Can't really tell which area you are referring to. In almost all cases the leak will be at a threaded fitting. Suggest you spray a soapy-water solution and let the bubbles tell you the exact location. Corrective action is to disassemble and re-tape/re-tighten the fitting and test again. If the leak is from the actual body of the reg (i.e. cracked housing) it will not be practical to repair.
