Will it work for a primo 3 gallon screw cap bottle?

If it’s a standard 3 gallon bottle with a long neck, it should. It is versatile and will fit most bottles of the same shape. However, it does not seal, like a cap. It gently lays on the top. If tipped over, all would come out.

Do I need to purchase the water bottle caps with hole in the middle for the pump to work?

Where can I purchase bottle caps?

I bought the 5 gallon jug. Do I need to buy new tops everytime I fill with water at the store?

My tops have an opening that is just perfect for the stream of water from the refill machines. I did not have to remove and replace them. Yay! Make sure you pull the plug up and out unless you don’t mind it floating in your bottle. https://www.amazon.com/dp/B00CN00BUE/ref=cm_sw_r_cp_awdb_btf_t1_oerIFbX4YWDX9

what is the size of the tube (diameter), where can I buy a similar diameter tube but much longer (several feet)?

The tube diameter is no more than about 2 centimeters. You can probably buy a similar tube size at a Home Depot/Lowes or any hardware store really.
