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.

70 Gas Cap for Non-Vented Filler Tube #172-12
All
1963-1969 roadsters use the filler pipe that is shown
above on the left side of the pictures, and the gas
cap that is on the left below. This is a vented
system. In 1970 cars that went to some parts of
the USA and Canada had an evaporative system that
required a non-vented cap, shown on the right
below.
These
are no longer available new; once in awhile we find
decent used ones. This was available in two versions;
this was the most common. The common 172-10 higher on
the page came out beginning with the 1967.5 cars. It
is about half the height and much more flat on top
than the older 172-17.
