replacing with stainless would be perfect. getting the firewall out would require some work. after laying upside down on my neck to fish the new
oil temp sending unit through the firewall i quickly realized i have no desire to do that again. i will probably throw some polish on it and that should be good enough as i do not want to spend days removing all the hole throughs in the existing.
I am a little bewildered why spf used beautiful stainless panels for heat sheds around the side pipes but not the firewall. that is one area where bdr has them beat.
