So, does the catalog list different caps for 68 and 71 trucks?

The 71 used a closed sytem as I remeber with a charcoal canister. The 71 cap shouldn't be vented. It's purpose was to contain all the vapors of the fuel to keep them from getting into the environment. The 71 tank should have the vent line deal that ran up into the cab corner didn't it? A big loop.....

The 68 tank didn't use the cansiter, the cap should be vented.
