Thanks, Steve. I've got a 304 stainless bend that I'll be welding to the
manifold, & could have sworn that I read online to use 308L rod for
stainless to mild steel, but I can only find one reference now, & it's on a
welding forum where someone says it's 'ok'. I'll try to find some 309L or
some 347 when I go to the welding shop this week.

Charlie
