Optional
Cap to Replace 172-12
We
have a cap (#172-14)
that can be used to replace the 1970 #172-12 cap for
the non-vented system. (Only works with 172-06 filler
picture above) It is the same as the original cap
except is not polished to the extent that the 70 cap
was, and it is a vented cap. For those of you that
have a fuctioning non-vented system to convert this
optional cap to a non-vented cap you would need to
have someone braze up a couple of small holes that are
outboard of the two rivets shown in the #172-12 cap on
the right, above. With some elbow grease and polish
you can probably get this buffed out to look close to
the original cap. It is much more economical than the
usually difficult to find original cap.
