A little late but, I finnaly figured out how to post pics!
My '71 also had the fuel smell problem. I knew the hoses were old and in need of replacing so in addition to replacing the hoses I thought I would replace the canister filter too. Hopefully this will help someone.
Canister out and turned upside down with old filter:
SANY0242
New filter:
SANY0245
The old filter just pulls out. I was surprised there is no screen to hold the carbon in place..
SANY0246
Install new filter:
SANY0248
Reinstall carbon canister:
SANY0253
install hoses and done.
