After inspecting my Andair gascolator during my annual and then reassembling it, I noiced I had a fuel leak between the body of the gascolator and the cap. On removing the bowl, I found the O-ring had ruptured. Reading the forums on this topic I see several post that list the O-ring size for the smaller internal filter. I need the inside diameter measement for the larger O-ring between the bowl and the cap. The size looks metric as posts list the ring size as 1.5mm thick. Neither ACS or the Andair site lists the O-ring specs. I can order from McMaster Carr if someone can tell me the inside diameter. Thanks!

Why can't you mic the spot the o-ring sits in if you don't want to use Spruce?
