Quick Gas Tank question

I posted last weekend that I had installed a new tank in my blazer. I got everything hooked up, vent, gas fill, etc.
Now the question:
There are two smaller hose/vent tubes coming out on each side of tank. I am pretty sure I can plug these, is that correct? What are they for?
The picture below is not MY tank, but you can see one of the tubes on the opposite side of the vent/filler tube side as an example.

I think the other two lines are for 1970 and later. Part of the emission controls. The lines hook to the evaporative emission control canister. Your 69 may not have this. If not as long as you have a vent tube up by the filler I think plugging them, or looping them together is your best option.
