If you still have the cloth covered lines you can have leaks and never see
them.  The rubber underneath the covering can become as porous as a cloth
and you will smell the vapors very clearly.  The problem is to tell which
line.  So I just replace all of them.

Also another strange item.  Last summer during the really peak hot days I
was developing a gas odor after driving for a while but seemed to trace it
to the gas cap. (a locking one)  with the 100 degreeF plus days recently the
odor was back extremely strong and traced back to my filler cap area.  I am
now going to examine the inside of the filler area where the filler neck
goes through the body.
