1970 Cutlass Fuel Tank Vent Hoses
I had to drop the fuel tank on my 1970 Cutlass Supreme to replace sending unit. The sending unit being replaced has 2 fuel lines coming from it. The question I have is what are the 2 fuel tank vent hoses coming from corner of tank supposed to be connected to? Both were just open not connected to anything. I expect some pollution item was removed. Should these be capped or what should I do? Having these hoses open does not seem like a good idea.

The vapor canister was required on cars delivered to California dealers on and after Jan 1 1970 and the rest of the country had the requirement for 1971 model production.

Edit: The neck of the tank does have a metal catch inside to hold the pump nozzle which can restrict the flow of pumped gas.
